University of Malaya, Faculty of Engineering, Dept. of Electrical Engineering UMIST Xilinx FPGA Based Multilevel PWM Single Phase Inverter pub Q T public Xilinx FPGA; single phase inverter In this paper a XILINX FPGA based multilevel PWM single-phase inverter was constructed by adding a bi-directional switchs to the conventional bridge topology. The inverter can produce three and five different output voltage levels across the load. XILINX FPGA is a programmable logic device developed by XILINX which is considered as an efficient hardware for rapid prototyping. It is used as a PWM generator to apply the appropriate signals to inverter switches. In addition to XILINX FPGA, Matlab/Simulink software was used for simulation and verification of the proposed circuit before implementation, Simulation and experimental results show that both are in close agreement 2006-12 published Engineering e-Transaction 1 2 Faculty of Engineering, University of Malaya 40-45 TRUE 1823-6379 http://ejum.fsktm.um.edu.my http://www.um.edu.my org [1] V.G.Agelidis, D.M.Baker, W.B.Lawrance and C.V.
