You are describing the differences a peak switched or zero voltage switched conversion systems. I have a patent on the latter from the 70's.

You are correct, but note that when we absorb nearly all the stored energy in one cycle or even one half cycle, the swing needs another push to do any useful work. The process is not automatically "repeated", but requires another shot of energy input.
This, to me, is very different than a class C oscillator operating in "resonance" where nearly pure sine waves are produced and only a small portion of the Q is lost per cycle.
The definition of quasi: a combining form meaning “resembling,” “having some, but not all of the features of,” used in the formation of compound words.
Although it may "resemble" a resonant circuit because it has some of the features (L and C) it is not strictly a resonant circuit in the pure sense (by actual operation) or there would be no need for engineers and organizations that classify inverter types to use the term "quasi".
You may resemble your brother, but you are not your brother.
We may agree to disagree, both being correct from two differing perspectives.
Yes,that is exactly what i was saying-peak switching and zero voltage/current switching-the later apparently more efficient.
I agree,i am not my brother-but we opperate in the same way.The more work we do,the more fuel we consume-as with the quasi resonant circuit.
So yes-i do agree with what you say ION,and ex is not incorrect with what he terms to be a resonant circuit.But myself and others here are looking at the brother that is doing useful work,while the other sits in his chair watching TV-just consuming fuel without doing any useful work.
But the question remain's-why dose the second watt meter in the video read more than the first?.There will be no high frequencies comeing from the GTI,as they are designed to match the Grid AC phase-this is why there called grid tie inverters.
It just seems to some that OU is not within our reach,and everything is dismised befor they them self do any testing.OU is very real,and it is right there with you-but blindly missed.You even touched on the existing OU machine your self ION-quote:You may resemble your brother, but you are not your brother.
Now lets look at how much fuel the human body consumes,and how much useful work it can do on that small amount of fuel-thats an OU machine if i have ever seen one.Nature provides the perfect energy converter,and maybe we should be looking more into how that all work's?.But it also makes it believable that an OU device can be built,and we should not dismiss something because of it's simplicity by means of faulse statements.
Quote Ex: 1) the coupling with the flat coil is at around 20 Khz thus the output current is at the same frequency
2) an inverter uses also frequencies at tens of Khz for operating.The input/output difference here is not beyond the experimental error: did you ever see the output from a cheap inverter? The signal is not sine, it's between sine and square often with an irregular shape.
And obviously the output wattmeter is not RMS nor it is designed to handle the high frequency components of the output signal.<<<What high frequency component of the output signal?.
As this is not a normal cheap inverter, this means nothing to the input or output of the GTI with the way romero had his setup.A rectified 20Khz ac frequency wouldnt need too much capacitance to get a smooth(or very close to)DC out.Looking at romero's setup,i would think 40 000uf would be more than enough.
Then comment 2-an inverter uses also frequencies at tens of Khz for operating.-What has that got to do with the AC output of the GTI? If this is how it converts the DC input to get it's AC output,then what dose that have to do with any part of what the watt meters are reading?.
These are comments that do not help in any way at all in finding out wether a system has merrit or not,and these kind of comments just confuse people even more.If i am to go out and spend $110.00 on a cook top,then i would hope that i would get information that will aid me in my reserch.To get anywhere,we must all stand together.This means putting forth information that has an effect on the outcome,wether that be good or bad for us.But negative comments that have no effect on the outcome ,just are not warranted.
