A Flyback Converter Fed Multilevel Inverter for AC Drives

Authors(2) :-Teenu Jose, Sreepriya R

This paper presents a flyback converter fed cascaded multilevel inverter drive having developed H-bridge. The DC supply required for the inverter is developed with a flyback converter with multiwindings at the secondary. An algorithm to determine the value of DC sources required for an N level inverter is also proposed. Multilevel inverter topology was developed in order to increase the number of output levels and to reduce the number of power switches, driver circuits and the total cost of inverter. Both 7 level and 31 level inverter was simulated and verified in MATLAB/Simulink environment. The values of DC sources were made different to increase the output voltage level without increase in number of switches and voltage source. This topology can be used for high power motors. THD levels of both the inverters are also compared in this paper.
