American manufacturers are importing European and Asian industrial equipment at an accelerating pace. The problem: that ...

Welcome to the first in a series of articles focusing on electrical calculation basics. This month, we'll discuss the most fundamental of calculations — those for current (I) and kilowatts (kW). We'll ...

A farmer is watering an alfalfa field 24 hours a day using a 3-phase 100-hp electric motor and adjustable speed drive (ASD). The farmer checks on his field to find the water not flowing and the pump ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

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 ...
