A single stage power factor correction converter for high voltage power and frequency applications

Abstract

This paper introduces a modified single-stage power factor correction (S2PFC) converter topology for high voltage, power and frequency (HVPF) applications which improves the power quality at utility AC side and at the load end. The modified proposed converter possess the ability of controlling the voltage and frequency independently and also simultaneously. The voltage can be controlled by PWM technique and also by dead time control which performs the boost operation. On the other side, frequency control can be obtained by using variable switching frequency. This paper presents the operation of the proposed converter topology, PWM switching scheme and MATLAB simulation results of the converter topology at a specific load are presented.
