The paper proposes a new topology of a boost type ac/dc PWM converter featuring high power factor, full control of the output dc voltage and high-frequency line filter inductor and insulation transformer. Its main advantage is the complete integration of a rectifier and an inverter stage, so that a compact converter with only four IGBT’s and six diodes is obtained. The integration poses some constraints on the line current control capability of the converter, which is limited. Nevertheless, the compliance with EMC standards (IEC 61000-3-2) is possible for a wide load range. The paper presents a detailed analysis of the topology, highlighting the design constraints and proposes a possible design procedure, which is then verified by means of numerical simulations.

Abstract

The paper proposes a new topology of a boost type ac/dc PWM converter featuring high power factor, full control of the output dc voltage and high-frequency line filter inductor and insulation transformer. Its main advantage is the complete integration of a rectifier and an inverter stage, so that a compact converter with only four IGBT’s and six diodes is obtained. The integration poses some constraints on the line current control capability of the converter, which is limited. Nevertheless, the compliance with EMC standards (IEC 61000-3-2) is possible for a wide load range. The paper presents a detailed analysis of the topology, highlighting the design constraints and proposes a possible design procedure, which is then verified by means of numerical simulations.
