Space Vector Modulated Three-Phase to Three-Phase Direct Matrix Converter

Being an "All Silicon Solution", Matrix Converter ( MC) has become main interest of researchers as a possible substitute of back to back ( B2B) connected converter topology with dc link storage. Lack of dc storage element is a main attractive feature of MC converter topology which can make it suitable choice for many traditional B2B converter topology dominated applications. In this paper, Space Vector modulation ( SVM) technique is applied for fixing the switching pattern of direct 3x3 MC. Here the concept of SVM technique for direct 3x3 MC is conceived by representing it in its equivalent B2B connected indirect converter topology and simultaneously applying SVM technique to both converters. Performance of direct MC is verified by simulation in PSIM environment. Simulation results are analysed on the basis of input power factor ( P.F), V/F ratio and input current THD.
