| Abstract |
In the paper, a single phase, sliding mode controlled inverter with three levels output voltage for fixed frequency AC generation is described. After a brief review of the sliding mode control theory, the way to obtain the three levels output voltage will be described from the theoretical point of view. Next a simplified approach will be shown. Simulation results are presented. In the last part of the paper the hardware implementation of the control and some experimental results relevant to a single phase, 5 KVA, 110 Vdc, 220 Vac, 50 Hz, IGBT inverter will be presented. |
