6.78 MHz High Power ZVS Class-D Development Board

Due to the problem that comes with hard switching method, manufacturers try to minimize the overlap to in turn minimize the switching losses by increasing the rate of change of current (di/dt) and voltage (dv/dt) in the switching waveform. This led to the soft switching or Zero Voltage Switching (ZVS). The ZVS is a conventional PWM power conversion during the MOSFET’s on time but with resonant switching transitions. Read more
