Digital Simulation of Photo Voltaic Based Cascaded Boost Converter for Voltage Source Inverter fed Induction Motor Drive

Solar energy is one of the important infinite source that maintains life on earth and is of clean energy. This energy can be converted to different forms as per our requirements. In this paper digital implementation of Photo Voltaic (PV) based cascaded boost converter (CBC)for voltage source inverter (VSI) fed induction motor is presented. The proposed PV model is based on a behavioral cell model that takes in to account of the environmental parameter of temperature and irradiance. And then its output is considered as input for CBC in which the low voltage is stepped up toa level that is required for the VSI fed drive. This kind of CBC system is implemented with only two switches and its synthesis will be explained in this paper. The comparison between SPWM and SVPWM is verified by using three phase VSI. The effectiveness of the proposed scheme is also presented through digital simulation using MATLAB Simulink.
