A Single Phase 11-Level Inverter for Photovoltaic Application

This paper presents a single phase 11-level inverter based on five buck DC-DC converters and H-bridge inverter topology with simple pulse width modulation method. The proposed inverter topology works in two operation steps; the first one for generating level and the second one for generating polarity. The pulse width modulation is employed to generate gating signals for power switches. The Separate DC sources can be replaced by renewable energy source. The complete system is simulated using Power Simulator Software for simulation results and micro-controller is used to generate gating signals, hardware results are presented to check the performance of the inverter in laboratory.
