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 ...

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 ...

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 ...

The LR2 line reactor series adds seven new frame sizes to match all GS, DURApulse, and WEG drives. The LR2 Series can also be used with a variety of other variable frequency drives (VFD) ...

Last month, we discussed low power factor and how resonance can disrupt facility operations. This month, we'll talk about harmonic filter design and various system parameters that affect filter ...
