AC-AC single phase matrix converter with harmonic filter and boost characteristics: A study

Abstract

An AC-AC single phase matrix converter with its unique characteristics is presented to reduce the harmonic of the input current and has the ability to step up the output voltage of the system which is the main analysis in this paper. AC-AC converter topology switching strategy is used in the SPMC which is controlled by the closed-loop current control or also known as active current wave-shaping technique. In order the AC-AC SPMC to operate and synthesize as a harmonic filter and voltage booster, the input supply current is being compensated by closed-loop current control to produce the SPWM signal to be injected to the switches used which are the IGBTs. The works has been done using Matlab/Simulink simulation and the results are being compared to the same simulation done in open-loop method without using the active current wave-shaping technique.
