Hysteresis current control for AC-DC converter using single-phase matrix converter fed permanent magnet motor

Abstract

In this paper, a computer simulation model of Hysteresis Current Control (HCC) technique for AC to DC converter fed permanent magnet DC motor (PMDC) using single-phase matrix converter (SPMC) topology is investigated. As the AC-DC converter fed PMDC motor yields a non-linear load, this can affect the generating of harmonics resulting high total harmonics distortion (THD) level hence low power factor. In addition, this phenomenon also have a set back in deteriorating the system operating performances. The use of HCC to achieve high power factor and low total harmonic distortion (THD) level is proposed. On the basis of the proposed modelling, the switching algorithm of the hysteresis control for the active power filter function (APF) is firstly studied and investigated. Simulation results are presented to verify the accuracy and feasibility of the proposed solution.
