Abstract :
A single phase, sliding mode controlled inverter with three levels of 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 of output voltage are described from a theoretical point of view. Next a simplified approach is 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 are presented
