Harmonics reduction using multilevel inverter with SMES by OHPDPWM technique

The Static synchronous compensator is a shunt compensation device based on the principle of power electronics. Recent development of FACTS devices provides the reliable solution to potential problems. A cascaded multilevel inverter with Super Conducting Magnetic Energy Storage (SMES) is proposed for reduction of harmonics content. Multilevel inverter based FACTS offers improved voltage quality, decreased switching frequency. Here OHPDPWM technique is applied to the Multilevel Inverter (MLI) to obtain better performance. The performances of different PWM techniques applied to the Multilevel Inverter (MLI) are studied and the simulation result was carried out.
