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 (+Vdc/5, +2Vdc/5, +3Vdc/5, +4Vdc/5, +Vdc, ‘0’ level, -Vdc/5, -2Vdc/5, -3Vdc/5, -4Vdc/5 and -Vdc) 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.
