Three-phase AC voltage regulator as part of an autonomous system

Abstract

In this paper construction of a system with the stabilization of the current value of the variable voltage and frequency based on AC-AC regulator with voltage boost with unity power factor function with PWM control is proposed. A mathematical model of the system is constructed. Results of investigation of the properties offered AC-AC regulators and their possible applications for stabilization of voltage in power supply autonomous systems, characterized by dual-range of change of the generated voltage are presented. The approach is based on the introduction of a high frequency variable voltage-additive supply voltage.
