Abstract

This study presents the simulation analysis of a PV based single-phase modified H-bridge eleven-level inverter. Multilevel inverters offer high power capability, associated with lower output harmonics and lower turn-off losses. This study informs a PV based multilevel inverter using a H-bridge output stage with four bidirectional auxiliary switches. The inverter is capable of producing eleven levels of output-voltage levels (+V_dc/5, +2V_dc/5, +3V_dc/5, +4V_dc/5, +V_dc, ‘0’ level, -V_dc/5, -2V_dc/5, -3V_dc/5, -4V_dc/5 and -V_dc) from the DC supply. Theoretical predictions of the proposed PV based single-phase modified H-bridge eleven-level inverter with MPPT are validated using simulation in MATLAB SIMULINK.
