| Abstract |
This paper proposes a control scheme for a single phase H-Bridge multilevel converter for photovoltaic applications. This control approach permits each H-Bridge module supply different power levels, allowing an independent maximum power point tracking of each photovoltaic (PV) panel. Since no intermediate stages such boost DC-DC converters are needed, a high efficient solution is obtained compared to the standard PV converter systems. Additionally, this topology offers other advantages such as the operation at lower switching frequency and low current ripple. Simulation results of a two series connected H-bridge rectifier with maximum power point tracking for different conditions are presented. |
