3. Flyback circuit ON phase: The MOSFET is switched on and a voltage is applied on the primary winding through the transistor. Energy is stored in the transformer’s core and the output Diode D1 ...

The transition from diodes to synchronous-rectification (SR) MOSFETs in secondary circuits of flyback converters increases with each new generation of MOSFETs, improving performance at little or ...

Power diodes, power MOSFETs, and IGBTs are explained, along with the origins of their switching times. Equivalent circuit models are refined to include the effects of switching loss. The discontinuous ...
