MOSFET body diode recovery mechanism in a phase
... EMI/RFI noise is reduced. The zero voltage condition occurs by the intrinsic MOSFET body diode conduction; an extremely low reverse voltage, occurring at no or low load operation, which could be not sufficient to guarantee the reverse recovery charge sweep out before turning off the MOSFET. In this ...
