Reducing Total Harmonic Distortion with the Optidrive ECO series.

Both AC line chokes and DC link chokes have historically been used with Variable Frequency Drives (VFDs) as a method to reduce the harmonic distortion generated. An alternative method which can provide even better results is by reduction of the DC link capacitance.

The reduced DC link capacitance is achieved by using film capacitor technology as opposed to the electrolytic capacitors used in conventional VFDs. Benefits of the film capacitor technology include a longer capacitor lifetime and removing the need for capacitor reforming.

Improvements in modern day IGBTs allow the use of the higher switching frequencies required to achieve the necessary control without sacrificing overall efficiency. There are limitations, in that the technology can only be readily applied up to around 100 Amps load current at present, as above this current, the heat losses from the IGBT are too great, and result in unacceptable efficiency reduction, however below this point, the gains are significant.

The benefit to reducing the DC link capacitance is a significant reduction in supply current harmonics at full and part load, which is of much more practical benefit since the majority of operation will be at part load. In addition, there is no reduction in the reliability of the design or resistance to mains voltage fluctuations, spikes or notches compared to a drive designed with a DC link choke, since the DC choke is not effective in these areas.

By utilizing higher PWM switching frequency, there are additional benefits such as reduced audible noise from the motor without derating. The reduction in peak input currents also result in lower stress on the rectifier stage.

Reviving Tesla’s Dream: The Future of Wireless Power Transmission

“My project was retarded by the laws of nature. The world was not prepared for it. It was too far ahead of time. But the same laws will prevail in the end and make it a triumphal success.” – Nikola Tesla

In the early days of radio technology, there was a crucial decision point that split wireless technology into two distinct paths. One path, pursued by Marconi and others, focused on electromagnetic wave transmission. The other path, championed by Nikola Tesla, aimed to minimize electromagnetic waves and use the Earth itself for energy transmission. While the world predominantly embraced the former, Tesla’s innovative approach was largely forgotten. Let’s explore Tesla’s lost art.

Tesla's wireless power transmission system, often known as his "Magnifying Transmitter," was a pioneering approach to sending electrical energy over long distances. Unlike today’s wireless technologies, which rely on electromagnetic waves, Tesla's design aimed to transmit energy through the earth, which he believed was more efficient.

Tesla showcased his system’s potential during his 1899 experiments in Colorado Springs. He successfully transmitted energy through the ground, illuminating bulbs about a mile away from the transmitter. Tesla saw this as a matter of engineering: just as a machine that can throw a rock 5 feet can be engineered to throw it 1,000 feet, he believed his system could be adjusted to transmit power across any distance on Earth.

Modern wireless technologies, such as radio, Wi-Fi, and cellular networks, use electromagnetic waves that spread outward from a source. These waves lose strength according to the inverse square law, which means signal strength decreases with the square of the distance from the source. This energy loss is a significant limitation for long-distance communication and power transmission.

Tesla’s vision was quite different. He recognized that while electromagnetic waves were effective for communication, they were inefficient for transmitting large amounts of power. As he put it, “I only used low alternations, and I produced 90 percent in current energy and only 10 percent in electromagnetic waves, which are wasted.” Tesla aimed to minimize electromagnetic radiation, which he considered to be energy-draining. Instead, he focused on transmitting energy through the earth, which he believed was more efficient and recoverable.

Tesla's system utilized a large coil known as the "Magnifying Transmitter," which generated a high-voltage, low-frequency current. This design featured significant self-inductance and minimal capacitance, producing a strong resonant effect. By accumulating and directing massive amounts of energy with minimal losses, Tesla aimed for efficient power transmission. As he explained, “I accumulate in that circuit a tremendous energy... I prefer to reduce those waves in quantity and pass a current into the earth, because electromagnetic wave energy is not recoverable while the earth current is entirely recoverable, being the energy stored in an elastic system.”

The scientific principles of Tesla's system include:

1. Resonant Circuits: Tesla's system used resonant circuits, tuning the primary and secondary coils to the same frequency. This resonance allowed for efficient energy transfer between coils, amplifying energy while minimizing losses.

2. Self-Inductance: A key component of Tesla’s system was self-inductance. A large coil with high self-inductance generated a strong magnetic field essential for creating high-voltage, low-frequency current. Self-inductance helped store energy in the coil’s magnetic field, critical for high power levels.

3. Capacitance: Tesla’s design involved large capacitors to store electrical energy. Capacitance was kept small compared to self-inductance to achieve desired resonant effects. The capacitors would discharge rapidly, creating high-voltage pulses for transmission through the earth.

To construct a system similar to Tesla’s, he advised:

1. Low Frequency, High Voltage Design: Build a large Tesla coil to generate high voltages at low frequencies. Ensure the design minimizes electromagnetic radiation and focuses on efficient energy transfer into the ground.

2. Loose Coupling for Resonance: Use loose coupling between the primary and secondary coils to achieve significant resonant rise. The coils should be inductively linked but not too close to avoid direct energy transfer.

3. Earth Connection: Establish a deep, effective ground connection to allow the transmitter to send electrical currents into the earth, utilizing its natural conductive properties.

4. Minimizing Radiation: Design the system to suppress electromagnetic radiation, aiming to retain energy within the circuit and direct it into the ground. Tune the system to maximize energy storage and transfer.

5. Energy Storage and Discharge: Incorporate large capacitors for storing and rapidly discharging energy to create high-voltage, low-frequency oscillations.

Tesla’s system faced significant challenges, including the need for large, expensive equipment. In 1914, he estimated the cost of his "Magnifying Transmitter" at $450,000—around $15 million today. These financial constraints prevented him from fully realizing his dream and unfortunately led to his public image as a mad scientist with unrealistic future visions. However, the potential applications of his system are vast, from global wireless power transmission to reducing infrastructure costs and powering remote areas. With ongoing advancements in technology, Tesla’s vision may be within reach.

Tesla’s system presents an alternative approach to wireless energy transmission, focusing on efficiency and long-distance power transfer over the broad dispersal of electromagnetic waves. While modern technologies have advanced in different ways, Tesla’s principles—especially his focus on resonant circuits and earth currents—provide valuable insights into alternative methods of energy transmission. Exploring these principles today could lead to innovative applications, such as more efficient long-distance power transmission or new energy transfer methods.

Wild Sky

“How long will it feel like?”

“Less than a second. Your time in the pod will feel so short that you’ll think something is broken.”

“Really?”

“Really.”

“Okay then, Sign me up.” Ellen didn’t particularly want to take a stasis pod instead of a hibernation cabinet, but the last time she went into hibernation, she had… complications upon awakening. She was severely injured from an error on warming, and lost her right arm, right lung and half of her liver. The organs were regrown, and the limb replaced, but her doctor warned her to not hibernate anymore. Ellen figured that was that, and she was stuck on this planet. 

Until she read the news on her pad a few years later.

“Volunteers needed for sapient level trials of a new technology! Free interstellar travel!”

Intrigued, Ellen checked it out. She would try nearly anything to get off this planet.  Especially since Trish left her. 

It had turned out that scientists at the university had developed a ‘stasis’ system. It created a field where time did not pass. Even better, power is only needed to create and break the field. Once set, the stasis field is stable. You could cook a holiday meal for one hundred people, put it in stasis, and take a serving from it until it was gone, safe in the knowledge that even if it took you weeks, each plate would taste as good and the first. From the perception of the meal, all the servings were taken at once. 

Figuring it was her only way off this rock, Ellen signed up for the trial. She was subjected to weeks of examinations by all kinds of doctors. She was the first candidate with regrown organs and artificial limbs as well, so the scientists were extra excited about putting her in stasis. 

After about half a year, she was approved for the program. The first trip was going to be just for a day, in the offices of the university. Should that one go without a problem she and the other candidates would be placed aboard a ship and sent wherever they wanted It would be one ship with dozens of pods.  It didn’t matter how many months they traveled to all the destinations of the passengers, no time would pass for them.

As Ellen settled into the stasis pod, she chuckled to herself. For something that she was going to only spend a few seconds inside, it was very comfortable. Cozy even. She settled into the seat and clipped a short cord from the pod to the sensor suite on her wrist. As she did, her name and vitals appeared in the clear window on the pod. 

“We have good telemetry Ellen, we’re going to set the field, all right?” The doctor peered over the lip of the pod. It was a good deal larger than a regular hibernation cabinet, and the doctor was standing on a little stool.

“How long will I be out?” Now that she was in the pod, she yawned.

“Like I said, just a day Ellen. We’ll see you Wednesday morning. There’s nothing to worry about.”

“Oh, I’m not worried, I was hoping I could get a nap, it’s so comfy in here”

The doctor chuckled. “It’s like that on purpose. The pods are designed to help put people at ease. That, combined with the mild sedative we gave you should make this no more scary than lying down in bed.”

Ellen blinked. A sedative? “No wonder I’m so tired. I’m high as hell!”

The doctor held up a hand. “Just a bit, and it’s fast acting. It’ll wear off by lunchtime, your time. All part of the waiver you signed.”

Mentally, Ellen shrugged. She did feel fine. Almost floaty. “All right Doc, whenever you’re ready.”

He looked down at his pad and made some notations. “Okay Ellen, we’re going to close the lid now.”

With a light hum, the lid game down. Ellen felt her ears pop as the pressure changed.

“Everything is green Ellen. As soon as the capacitors charge, we’re going to set the field. See you tomorrow!” The doctor’s voice sounded tinny over the connection. 

“All right Doc, see you tomorrow!”

“Field set in three… Two…”

There was a flash of silver, and it was dark in the pod. Ellen looked at the lights glowing inside. The window on the top was mirrored and she just saw a reflection of herself. Woman, late thirties, hair closely cropped to hide the grey and for ease of care; she never felt really ‘girly’ and didn’t keep her hair long or wear much makeup. She had just recently broken up with her long term girlfriend and thought this would be a source of an interesting story for future dates if nothing else. 

Funny, the doctor had said that her perception of time would be so short that she would wonder if it had worked at all. She was still lying here wondering what was going on. Maybe the doctor had misrepresented how long it would feel like for her to put anyone with claustrophobia at ease.  

They checked her for that though. The psych said she had none.

She wondered how long it had been. Surely, this was the right amount of time?

How long had it been?

She counted heartbeats.  She knew her heart rate was around 70 beats per minute, so she could get a rough idea how long she was in the pod from counting heartbeats.  In the silence of the pod, her heart was loud in her ears. She even thought she could hear her blood flow. 

After about ten minutes of counting by her reckoning she was bored and looked around more.

How much longer could it be?

Surely they’ll be here now?

All of the indicators on the side of the pod were dark. The telemetry information must reside outside of the stasis field. She was alone with her thoughts.

Isn’t it done yet?

There was a hum, rising in her ears and becoming louder and louder. Rising to a deafening crescendo it ended with a click like a relay. The top of her pod turned clear.

An unfamiliar ceiling. Maybe they moved the pod in between yesterday and today. It was beige with diffused lighting which didn’t seem to come from anywhere. Even though the field had disappeared, the lid still didn’t open.

A moment later, the lid opened with a pop of pressure and Ellen’s ears popped again. Unfamiliar smells flooded the pod. None were unpleasant as such, but she didn’t recognize any of them. Like, a new apartment or a friend’s house, it smelled unfamiliar. 

Ellen sat up. “Wow, that felt way longer than just a moment Doc, for the next group of people you should… tell… them…” 

Ellen looked around and her eyes focused.

The doctor wasn’t there. 

Three… beings dressed in long, emerald green robes stared back at her. They weren’t human.

They weren’t human! What the hell was going on?

“What’s going on? Who are you?”

The middle being stepped forward. They spoke. Ellen didn’t understand the language, it had a warbling, vibrating quality, almost like you would have to feel it as much as hear it. At their… waist was a box. It spoke in hundreds of languages, almost all at once. While it spoke a blue light shone on her face. With a warbling noise as it hunted and searched, it finally said something she understood. It said “There… has been… a sit-u-a-tion.” 

Wild eyed, Ellen looked up at the head of the one who had the box that spoke. They had large, compound eyes, like a fly and their faces were an iridescent green.

There must be some mistake. A trick, a prank. Panicking, Ellen jumped out of the pod and searched the room. She was nowhere near the laboratory at the university. She had no idea where she was. The room was the same uniform color of the ceiling with the invisible diffused light. Other than the three beings and her pod, the room was empty. There. A door behind them. She ran out the door, down a hall. She was beyond thought now, she just needed to get out. 

Things will make sense when she’s somewhere else.

She ran toward a door that looked like an exit and was outside. 

She looked up and gasped. She was so surprised that she lost her footing and fell down. Rolling on her back she looked up and saw the sky.

A wild sky. Turquoise with clouds in cotton candy pink. Looking further she could see a… structure in the sky. A large latticework, trailing off into the distance, made hazy by the atmosphere. The structure must be very high in the sky, and very very large.

She didn’t know how long she laid there, staring up at the strange sky. Eventually the being from the room with the box came up to her. He bent low - at least they have knees. Ellen actually stopped her panic to have that thought and the idea that at least they have knees brought her a small measure of comfort.

“We… are… sorry….” The box was getting better at translating. She wondered if she was able to help it when she shouted at them.

“How long has it been?” Her eyes flicked away from the sky to the compound eyes of the being.

“We do not… know…” They made a gesture with their hands. 4 fingers. “A long… time.”

Ellen wept. What else could she do
