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 ...

Seasoned equipment designers have long known that an EMC compliance “pass” on an end product is not guaranteed by simply using compliant components. The reasons are varied. Compliance tests on an ...

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 ...

When failure is not an option, high reliability EMI filters deliver superior high-frequency EMI suppression for ...

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 ...

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 ...

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 ...

The Nature Index 2025 Research Leaders — previously known as Annual Tables — reveal the leading institutions and countries/territories in the natural and health sciences, according to their output in ...
