Abstract :
Multilevel inverter using cascaded H-bridge inverter with separated dc source (SDCSs) is introduced in single phase. The output voltage is the sum of the output of each H-bridge cell. The output voltage waveform is ideal with suitable switching angle estimation to produce required fundamental voltage. This paper presents the simulation of 5-level cascaded H-bridge multilevel inverter with selecting different switching angle and Newton-Raphson method is used for angle optimization. Simulation work is done by using MATLAB/Simulink software.
