WebMOSFET, and that neither of these is a function of switch-ing frequency. In general, a higher switching frequency and higher input voltage require a lower QG (gate charge) to cut down the switching losses in the switch MOSFET (Q1). For a rectifier MOSFET (Q2), low R DS(on) is most important, but don’t ignore the gate power. Also, changing the ...

WebActive rectification, or synchronous rectification, is a technique for improving the efficiency of rectification by replacing diodes with actively controlled switches, usually power MOSFETs or power bipolar junction transistors (BJT). Whereas normal semiconductor diodes have a roughly fixed voltage drop of around 0.5-1 volts, active rectifiers behave … WebG 1-158); see also Minerals Yearbook, 1945, "Statistical Summary of Mineral Production," p. 33.
