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 ...

Beware! The behavior of a part outside its operating specifications is not always predictable. Beware! The behavior of a part outside its operating specifications is not always predictable. In my ...

Almost all off line switching power supplies over several kilowatts of output power use a three phase bridge rectifier. Typically, it comprises a six diode bridge and a DC bus filter capacitor. A ...

The quest for higher power and greater efficiency in all power supplies never ends, especially when it comes to all heavy-duty converters. Some examples are power supplies used in data centers, ...
