The active filter - A new component of energy-saving electric drive systems

Abstract

The results of the development of a mathematical model of an active rectifier constructed using fully controllable power elements - insulated gate bipolar transistors, are given. The rectifier operates in the PWM mode. A vector control system is synthesized, which, under conditions of network voltage fluctuations and load changes, stabilizes the active rectifier output voltage and ensures bilateral energy exchange with the power supply network when regulating the network power factor and forms nearly sinusoidal currents consumed from the network. The results of modeling are given.
