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 ...

A research team led by Prof. MENG Guowen and Prof. HAN Fangming from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), along with Prof. WEI Bingqing from the University ...

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 ...

The Type PFCH capacitor series from Cornell Dubilier Electronics, intended for the ac output of large inverter systems, filter undesirable harmonics before power is delivered to the grid or load. The ...

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 ...

Part of the designer's average 'EMI troubleshooting day' may involve taking a core from the shelf and just winding some turns on it. But what if he is really struggling to bring up the inductance and ...

Using EMI filters to counter strong electromagnetic waves and unwanted electric currents induced in a circuit.

Full-wave rectifiers with capacitor filters are, without question, the workhorse — and the unsung hero — of the modern electronic world and for the gadgets we have come to enjoy. That being said, it ...
