Space Vector Pulse Width Modulation (SVPWM), Insulated Gate Bripolar Transistor (IGBT) The Z-source inverter is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. The Z-source concept can be applied to all dc-to-ac, ac-to-ac, ac-to-dc, and dc-to-dc power conversion whether two level or multilevel. Multilevel converters offer many benefits for high power applications. Z-source concept was extended to neutral point clamped inverter. The contribution of this paper is the digital implementation of SVM technique using 8-bit microcontroller for Z-source NPC. The proposed system uses 8-bit PIC 16F877A microcontroller to generate SVPWM (Space Vector Pulse Width Modulation) signal needed to trigger the gates of IGBT bridge of the multilevel inverter. This method has the benefits in terms of implementation and harmonic performance. By this method, the operation of Z-source arrangement can be optimized and implemented digitally without introducing any extra commutations.
