Abstract

This study presents Field Programmable Gate Array (FPGA) implementation of Sinusoidal Pulse Width Modulation (SPWM) technique for 5-level Cascaded H-Bridge Multilevel Inverter (CHB-MLI). The fast and easy generation of switching signals for multilevel inverters (MLI) which has complex switching schemes is an important issue. In addition, because of parallel processing, the use of FPGAs in the field of power electronics has increased. MATLAB-Simulink software and Xilinx System Generator (XSG) are used to analyze CHB-MLI and generate architecture of PWM signals which embedded in FPGA. After implementation on Digilent Genesys II FPGA board, the experimental gate signals waveforms are observed on a digital oscilloscope.
