Abstract : In this paper, an asymmetrical cascaded H-bridge 81 level inverter powered by a single photo voltaic (PV) unit is presented. The PV unit drives an interleaved soft switched boost converter that drives a simple three level inverter, which in
turn drives a multiple secondary winding transformer. The AC output of the four isolated secondary windings of the
transformer is rectified and filtered to deliver four isolated DC voltages in the ratio 1:3:9:27. The system incorporates
maximum power point tracking at the front end boost DC-DC converter level. Overall reduced THD is achieved by
strategically spacing on the time axis, for each AC cycle, the discrete voltage levels of the 81 level inverter. The
mathematical formulation, the results of simulation in the MATLAB/SIMULINK environment and the results of
experimental verifications are provided.
