Xilinx FPGA Based Single Phase Five-Level Cascaded Z-Source Inverter

摘要

This paper presents a single phase five-level cascaded Z-source inverter with reduced number of switches for PV/FC/Wind power applications. The inherent benefits of z-source inverter are higher boost gain and fault ride through capability compared with the traditional VSI and CSI inverters. Therefore five-level Z-source converter is simulated in MATLAB/Simulink environment and the generation of control pulses with the help of Xilinx System Generator is presented. A prototype model is developed to validate the theoretical concepts through experimental and simulation results.
