Design and simulation of five level cascaded inverter using multilevel sinusoidal pulse width modulation strategies

Paper proposes design and simulation of single phase cascaded five level inverter. The inverter can produce five different output voltage levels across the load. The multilevel sinusoidal pulse width modulation switching strategy was used and THD value for every scheme was analyzed. The main advantage of this technique is the ability to reduce harmonics. MATLAB/SIMULINK software was used for simulation and verification of the proposed circuit for implementing FPGA based five level cascaded inverter. The proposed circuit produces high output voltage without use of transformers and lower electromagnetic interference.
