Old radios often had selenium rectifiers to convert AC to DC. The problem is that the old units, dating back to 1933, are prone to failure and to release dangerous chemicals like hydrogen selenide. [M ...

Replacing the silicon rectifier diodes in a full-wave bridge with N-type MOSFETs eliminates the V f drop in each conducting pair. The effects of the gain in efficiency are not trivial. To accomplish ...

With Linear Technology’s LT4320 ideal-diode bridge controller, power supply designers can replace each of the four diodes in a conventional full-wave bridge rectifier with a low-loss N-channel MOSFET.
