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 ...

Designs often require synchronization of two power converters within the same piece of equipment. Doing this fixes the noise at a particular frequency and eliminates the intermodulation effects. With ...

Using sophisticated power electronics and communications systems to improve power system efficiency, flexibility and reliability is increasing interharmonic distortion and putting new equipment ...

A “loose neutral” in a residential location can cause equipment damage and even a house fire. An open neutral may start as a high-resistance connection that shows subtle signs in waveform capture data ...
