For PVA renewable source the output voltage is fluctuating as the solar irradiation is variable with respect to time. In conventional methods to control the DC voltage output of the PVA DC-DC booster converters are used. These converters don’t have high gain and also the ripple of the DC output voltage is high. The conventional PWM DC-DC booster converter is replaced with a feedback controlled dual switch converter for better control of output DC voltage with higher gain and reduced ripple. In this paper, the output of the dual switch converter is fed to controlled six switch inverter running a permanent magnet synchronous motor. The motor is controlled with a reference speed control technique for change in variable speed and torque operations. The input voltage of the converter is also made variable with respect to time with change in solar irradiation; the response of the proposed converter is good even for this condition. MATLab/Simulink is used to design all the modules of the proposed work.
