We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

A major cause of losses in a conventional power supply using a 50/60-Hz transformer is the bridge rectifier. This article shows how to build a “greener” rectifier, substantially reducing losses by ...

Linear Technology has released a controller chip that turns four n-mosfets into an active bridge rectifier and cut the expected voltage drop of a bridge from 1.2V to under 100mV, dramatically cutting ...
