Hi
A self-oscillator circuit based push and pull MOSFET and the concept is very similar to the Royer Converter as shown below. This circuit comes from MIT textbook where engineer experimented with wireless power transfer. In fact I have no interest in wireless power transfer but I am interested to understand the circuit but I am struggling at the moment. I would be grateful if you provide any explanation.
As far as I know that two MOSFETs need to generate square waveforms (PWM) which come from the current within the the centred tap transformer or two inductors when powering at DC voltage.
I am struggling to understand what is the use of the diodes connecting to the gate of MOSFET?
