Abstract


This paper presents, the design and simulation of 11-level Cascaded H-bridge DC-AC Grid-tied Inverter for the application of solar panels. A 200w solar panel connected to each inverter bridge. OPALRT lab was used as the hardware in the loop (HIL) real-time control system platform where a Maximum Power Point Tracking (MPPT) algorithm was implemented based on the inverter output power to assure optimal operation of the inverter when connected to the power grid as well as a Phase Locked Loop (PLL) for phase and frequency match. A novel SPWM scheme is proposed in this paper to be used with the solar panels that can account for voltage profile fluctuations among the panels during the day. The experiment is clearly verified with simulation results.
