Abstract:
The PV power generation have low efficiency due to the various constrains. This thesis gives a proposed method to reduce the THD using soft switching technique. The PV cell is connected to Multi-Level Inverter (MLI). In order to improve the efficiency. The project proposes an advanced H-bridge multilevel inverter which varies from the conventional one from the number of power devices used. The proposed seven level multilevel inverter has minimum number of power devices compare than conventional. MLI have emerged as attractive high power medium voltage converter to the reduce harmonic component in the output current due to filter. A novel PWM technique is used to generate the PWM signal for inverter switches and to reduce the THD level using soft switching technique
