Abstract

In this study presents the Trans Z source inverter with respect to the effective Photovoltaic (PV) power generation based system for different kind of AC loads Conditions. The most demand of solar array can be used for improve the operating life and high efficiency of power generation system. The Trans Z source consists of two voltage fed and current fed inverter for power conversion purpose. It gives the higher voltage gains while keeping voltage stress low and also reducing the Z-source network to one transformer and one capacitor. The single diode dynamic model of PV based proposed system can be used to extract the maximum power generation. In this study proposed the control strategy of various carrier dispositions used for R and RL Load condition. The comparison study of PD, APOD and POD PWM techniques have been carried out by Total Harmonic Distortion (THD). The proposed inverter has been used to produce the three level based output voltages by using controller unit. The proposed topology also can be applicable to induction motor for verifying the soft start capability. The simulation results have been analyzed and verified by MATLAB/SIMULINK software tool.
