Easy,
It is difficult to get current readings on the primary coil due to the fact that when the HV transformer comes on, our test equipment gets erratic and can get damaged (have lost a few meters already). We are inferring based off of what we can measure on the output. I measured 53ma pkpk...

Easy,
This circuit is built and we have been using it for a number of years, the 30-40 watts is a measured output not theoretical. Our power supply is max 10 amps at 15 volts so it is not possible to drive 35 amps through the primary. The transformer is also only capable of 100...
Sorry, secondary output power is between 15-20 mA rms so 30-40 watts. Primary input current is 2-5 amps based on input voltage selection which also amounts to 30-40 watts.
Primary coil V+ is between 8 and 15 volts adjusted in eight steps to change output for various treatments. Feedback coil V+ is approximately 2 volts but is varied somewhat by the feedback coil interaction with the secondary coil. Secondary output is around 20kV but also varies based on the...
Thank you Brad,
I spent some time trying to build this circuit in a simulation hoping to get some answers but I know nothing about it. The biggest thing that stopped me was not being able to find an appropriate transformer with our feedback coil which is integral in our design. Is there a way...
Easy, the circuit as shown is what we are currently using, our application requires the feedback coil to detect varying capacitance from the output coil to alter the frequency of the entire system dynamically while it is running. Can you explain (reverse diodes are better across the B-E - a...
Yes, the saturation flux of the transformer is correct, my terminology is poorly worded. Our modified Royer utilizes the feedback coil to detect varying capacitance on the output which alters the frequency of the entire system dynamically while it is running, this is a desired operation of our...
So I have a slightly modified Royer oscillator circuit that is driving a high voltage RF output for a frequency based medical device. The transformer has a center tapped primary coil with a center tapped feedback coil driving it so that the system runs at the resonant frequency of the saturated...
