Minimization of Unbalance in Hybrid Power System Using Three Phase Four Leg Inverter with Different Modulation Techniques
Abstract
In this paper, a three phase four leg inverter is designed. It is applied to Hybrid Power System (which is a combination of power system and local renewable energy). In H.P.S, if the load on the distribution side increases there occurs unbalance. These unbalance are minimized by using three phase four leg inverter. A comparative study of Inverted Sinusoidal Pulse Width Modulation, Third Harmonic Injected Pulse Width Modulation, Space Vector Pulse Width Modulation, Delta Sigma Modulation Using Space Vector approach has been made. Photovoltaic Cell is simulated in Matlab Simulink in order to implement hybrid power system.
