Reflector-pump network for preempting AC power supply harmonic distortion and for satiating the complex harmonic power demand of a rectifier
Abstract
A reflector-pump network is provided for insertion between an AC power supply source and a full-wave rectifier in an AC-DC power converter. The complex harmonic current demands generated by the full-wave rectification process are satiated by a pump in the network. Such complex harmonic current demands are further isolated from the AC power source by the reflectors in the network.
