This 99.7% Inverter Breakthrough Can Revolutionize Solar & EVs!

I am an Electrical Engineer and specialize in EMI and EMC testing. I am interested to see more about this technology and how it is different from similar inverters. The manufacturer claims that their algorithms are the key driver in increasing efficiency, so I would like to know more about this. Anytime you have any switching of electricity, you generate broadband noise. That’s just physics. The Fourier Transform of a unit impulse (delta function) is an infinite line located at the y value of 1. I don’t know how you can avoid a fundamental law of physics with a computer algorithm! Please show us their evidence and release peer reviewed scientific papers! Thanks for diving into this technology. If it really does work, then this may really benefit the world.

Is it just me, or did this completely fail to explain how this actually works?

yes. you just watched an entire ad.

The company that you are doing a story about is sponsoring the video. Therefore, this is a commercial.

OK, something here is missing. I have been a design EE for 30+ years :(,ZVS, PWM, etc. etc. etc. is nothing new and nothing that was previously unknown. We have been doing some form of this for years now. Efficiencies in excess of 90% is almost trivial and 95% with a little more effort. More so efficiency is typically highest at the higher end of the load and varies over load - you can't get away from the math. EMI is a problem long solved and is typically at switching frequencies not solved with big heavy capacitors, though sometimes when you lost control of your return currents for whatever reason and all else fails your big heavy shielding is necessary. Again, I may be missing something here, but this just sounds like a tweak or IP on something everyone took for granted and even better marketing. All the same, thx for sharing the content is appreciated.

As a fellow Electrical Engineer with a Master's degree in electronics and control systems, I'm curious about the distinction between this new 'zero switching' technology and traditional soft switching methods. Soft switching, whether it targets zero voltage or zero current, typically occurs close to zero voltage in practical applications. This concept isn't new; it has evolved significantly thanks to advancements in microcontroller capabilities and algorithms. While implementing soft switching is technically challenging, it is a well-established technique in the field. I will just add that it's pretty hard to impossible to switch at zero so there will always be a transition period between ON and OFF that's why they didn't claim 100% efficiency

I'm not liking the new "shilling" direction of this channel. First it was John Deere, now this. Worrying.

Why is this so revolutionary. I was designing hardware 40 years ago using ZVS . Haven’t most inverters used ZVS for years?

Being a former Analog IC designer, designing switching regulator IC's, semiconductor companies have been chasing the switching losses for 20 years. There will never be a zero switching loss goal based upon the physical realization of the task. There is always a transition loss, it just can be reduced by clever design. I suspect that what the company mentioned is doing is reducing the reverse recovery period by using a synchronous rectifier, reducing the time and losses of the normally used reverse recovery diode losses, commonly found in low frequency (i.e. 10 kHz) switching regulators. Most high current switching regulators operate at 50kHz range due to magnetic materials being used. Operating at 10 kHz could reduce switching losses by a factor of 5 but the magnetic materials get larger for this frequency. Many high efficiency switching regulators operate in the megahertz region to reduce the size of the magnetic (inductors) requirements but that comes with electro magnetic interference (EMI) issues that interfere with even modern electronic systems.

How much of this stock did you buy before dropping this video? wow

The mosfet switches when 0 volts and the extra energy gets oscillated between capacitors and inductors with resistor in between. This keeps the mosfet cool by switching at zero volts. You can make the circuit at home on your rework bench.

I'm not sure why everybody is so upset. He used to pitch EcoFlow as the best storage system on the planet and has now switched to pushing some other brand. Every once in a while, he actually talks about some actual new technology, but mostly he's a pitchman.

The current fall you show at 4:17 starts when the switch opens. In actuality, the fall doesn't start until the voltage across the switch is very near maximum. This is due to inductance in the circuit that keep current flowing. And, results in much higher switching losses. Zero current or zero voltage switching isn't new, it has been used for decades. By driving a resonant circuit, you wait until the voltage, or current swings to zero to open the switch. Also, switching at 10KHz, being in the audio range, would be very noisy. Most inverters operate over 20KHz, up to many MHz.

Hey Ricky, I see a lot of haters in the comments. With all due respect, imho I think a quick disclaimer at the start would avoid most of it. People are super sensitive these days. I didn't view it as an "infomercial" but I can see how the others did. Bills have to be paid and everyone has their own opinions. Keep doing you. Enjoy your Sunday.

I live in a motorhome. This would be a TREMENDOUS deal for RVers - probably greater than for EVs.

OK, so basically if this software is used with the right hardware you can get a few percent efficiency gains. A, while the specific code can be copyrighted the concept can't so if it's viable everyone building converters will copy it. B seems some hardware changes need to be made to make it work so only new or major retrofits could put it in BUT the system has to be as durable and as cheap to implement in grid scale because A few percent in efficiency at the production level of cost is easily out weighed by cost or maintenance or components service life.

The 99.7% efficiency I assume is for the switching losses. They may be able to reduce the switching losses to this level but you still have the internal resistance of the IGBT (or other switching device) which no amount of clever software will remove.

Bro. Pushing that ticker symbol hard.... Times must be tough for Ricky. Don't lose your morals my guy.

That is cool. I want to install a new Enphase panel based inverter solar system . Solves so many problems that combiner systems have.
