A Programmable Source Based on Multi-level Buck EIE inverter connected to a power factor correction stage composed by a single-phase hybrid rectifier

Abstract

This paper presents a power factor correction stage connected to a programmable source based on the Buck EIE converter Topology. The strategy used to ensure the unitary power factor is based on the use of the single-phase hybrid rectifier, which has the purpose of providing voltages at their outputs for the correct supply of the two cells that make up the Buck EIE converter. It was developed the computational simulation model, including the calculations of the passive elements and the control strategy applied to trigger the electronic switches.
