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 ...
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 ...
The more common approach to manipulate the incoming AC wave so that both halves are used to cause output current to flow in the same direction is the use of full-wave rectifiers. A full-wave rectifier ...
The electronic ballast circuit block diagram (see Fig. 1) includes the ac-line input voltage (typically 220 Vac/50 Hz or 120 Vac/60 Hz), an EMI filter to block circuit generated switching noise, a ...
