In inverter system, it is necessary to control the output voltage. This paper presents study and implementation of bipolar sinusoidal pulse width modulation (SPWM) technique for a single phase H-bridge inverter that is commonly used to regulate the magnitude and frequency of the inverter's output voltage. Bipolar SPWM modulation technique was implemented on the inverter system and total harmonic distortion (THD) for the scheme was analyzed. The scheme was simulated using PSpice/Orcad and MALTAB/Simulink platforms and the validation in real time was done using F28335eZDSP.

In inverter system, it is necessary to control the output voltage. This paper presents study and implementation of bipolar sinusoidal pulse width modulation (SPWM) technique for a single phase H-bridge inverter that is commonly used to regulate the magnitude and frequency of the inverter's output voltage. Bipolar SPWM modulation technique was implemented on the inverter system and total harmonic distortion (THD) for the scheme was analyzed. The scheme was simulated using PSpice/Orcad and MALTAB/Simulink platforms and the validation in real time was done using F28335eZDSP.
