Performance analysis of SPWM control strategies using thirteen level cascaded multi level inverter

In recent years multi level inverters are used high power and high voltage applications. In this paper propose PWM control strategy thirteen level cascaded H- bridge multi level inverter. This method introduce sine wave is compared with the triangular carrier wave with different phase relationship. The carrier based Phase disposition PDPWM, PODPWM, APODPWM have been analyzed in this paper. The PWM control strategy method for multi level inverter to reduce the total harmonics distortion in the output waveform. The simulation is done by matlab / simulink environment.
