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 ...

Although SPICE can be a powerful tool, there are pitfalls in relying solely on simulation. To avoid unpleasant surprises, it's imperative that a SPICE simulation be anchored to a detailed ...

An electrical device that converts alternating current (AC) to direct current (DC) is the rectifier. The simple process of rectification produces a type of DC characterized by pulsating voltages and ...

Not all UPS designs are the same. As a result of cost savings in the very competitive UPS market, some designs may not have the highest level of component reliability. Capacitors are an integral part ...

The input stage of an off-line power converter usually contains an LC averaging filter. A common practice is to damp the LC filter using additional reactive/dissipative components. In this article, we ...
