Abstract

This paper presents the new generation of advanced gate driver circuit based on IR2110 device for a Single-Phase Matrix Converter (SPMC) circuit topology that uses MOSFETs or IGBTs switches. The new generation of gate drive circuit uses less number of components, since a single IR2110 device can drive two power switches, thus reduce power losses and minimize the complexity of conventional circuit. An additional isolation of the upper and lower sides of IR2110 device features additional protection to the proposed gate drive system. As a result, the proposed gate drive circuit just uses four IR2110 gate drives in order to control eight switches of SPMC circuit, thus, solve the conventional bulky gate drive circuit problem in SPMCs operation.  This is in line with the international power electronic technology road-maps to reduce losses, cost, volume, therefore to raise up the power density of power electronics converters. Validation have been done through the experimental test-rig. As a result, such new theoretical enhancements can be used as a novel foundation of future high power density of SPMC circuit topology and in-line with the Fourth Industrial Revolution (IR 4.0) which were characterized mainly by advances in technology

Abstract

This paper presents the dynamic analysis of the high-power factor three-phase ac to dc converter using current injection hybrid resonant technique in order to investigate the characteristics of the output voltage, line current, DC-link voltage and the resonant current of the proposed converter. The dynamic analysis have been developed based on a separate analysis of the rectifier line-frequency operation and at the resonant circuit high-frequency. Converter circuit analysis have been performed based on the operation at the fundamental frequency. The power balance relation method has been included in order to match the line frequency equation with the high frequency resonant stage equation. This analysis can be envisaged to be the heart of the small-signal model to design the output voltage regulation and maintain a high-power factor input line current of the proposed converter.
