The third video covers filtering circuits, and the fourth is the best explanation of why you need a flyback diode when driving a motor (an inductive load) that we’ve seen yet.

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 ...

Zetex has announced a synchronous rectifier controller for flyback converters. Combined with a discrete power Mosfet, the ZXGD3101T8 ‘zero point detector driver’ replaces Schottky and other diodes to ...
