Abstract

This paper deals with a grid-connected five-level H-bridge inverter and the control scheme for its use in PV application. The topology proposed is the combination of six H-bridge inverter modules, two in each phase. The proposed inverter converts dc power into ac power and it is used for high-power applications. For inverter control, PI-based control scheme is developed. To generate gate pulses, SPWM technique is used for H-bridge inverter. A simple and effective control algorithm is implemented to regulate the inverter output. The performance of the system has been validated by simulation results and experimental analysis is carried out using FPGA-based coding in Spartan 3A DSP kit.
