According to the IEEE Standard Dictionary of Electrical and Electronic Terms, power factor (PF) is defined as the ratio of the circuit power (watts) to the circuit volt-amperes. This is described by ...

comprise a transformer, rectifier, and filter capacitor. Many single-voltage power suppliesconsist of a transformer, arectifier, and a filter capacitor, as shownin Figure 1. This circuit is ...

Many sensors have a small analog signal that rides on top of a larger dc pedestal. For these circuits (Fig. 1), the signal must be ac coupled and amplified before it’s digitized. The feedback of an ...

Adapted from an ac-output resonant half-bridge inverter circuit, the resonant CLC (capacitor-inductor capacitor) dc-dc converter employs a π-filter loaded by a rectifier. High-frequency power ...

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 ...

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 ...
