Verpies tell me about this load controlled oscillator Mazzilli, wish to make one and install myself a variable choke and a bank of caps, hook up a frequency counter and play with an iron and copper ground was per old scientist. Can this be done ? I thought this oscillator relied on the value of choke and capacitor on the primary side, so you say the secondary load will add the reactance component of secondary and thus change the frequency of resonance on the primary

I'M looking to build a device, but first, tools matter. Must have a good durable oscillator, still researching.

I once had problems with Mosfets blowing up, my research indicated that its the commutation that did this and not the heat generated.

Here is an amplifier that I designed wich worked to suppress durability issues, it was for lower than 50 kHz tho.

Also theres a sine generator, 3 phase. It was a rather expensive design, a single supply scheme just did not give me the best wave as dual.

It's that circuit that everybody is building and wrongly calling a "Royer oscillator".  For example see here.

You can play with anything.  If you play with an iron rod in a HF coil, then remember that its properties (such as permeability, resistance and skin depth) will change when it becomes saturated or hot. 
Note, that my mentioning of an iron rod does not constitute an advice to put it in the ground or play with any ground whatsoever.

The frequency of the Mazzilli circuit does not depend on the inductance of that DC choke much (though power consumption does).
The frequency of the Mazzilli circuit chiefly depends on the capacitance of that capacitor C1 and the inductance of the primary winding. 

The latter also depends on the mutual inductance with the secondary winding and consequently on the load across the secondary.  That's why I call this circuit a Load Controlled Oscillator.

..... Mazzilli Vladimiro described in an e-mail how this circuit works:[/size] [/size]The Royer circuit is a push pull, current fed, zero voltage resonant converter.[/size]At starting T1 go in conduction for first through the 820 ohms resistor at point B. The conduction of T1 through D1 keep low the gate voltage of T2 that remains open.   .....

[/size]
therefore; it's not wrong, it's a synonym.[/size]

No, Royer oscillator has a 3rd primary winding and looks like this.

What is being measured?
Why is the rise time of the upper trace so long?

Dear Verpies.

I think this might "Cut the mustard"!!

Ch1 Reference frequency of PWM. Ch2 Received signal Piezo 2.

Cheers Grum.
