High Voltage Gain DC-DC Boost Converter based Photovoltaic System Using Multilevel Inverter fed Induction Motor

Abstract

Solar energy is the most low cost, competition free, universal source of energy as sun shines throughout. This energy can be converted into useful electrical energy using photovoltaic technology. The effective operation of Induction motor is based on the choice of suitable converter-inverter system that is fed to Induction Motor. Converters like Buck, Boost and Buck-Boost converters are popularly used for photovoltaic systems. This review is mainly focused on high efficiency step-up DC/DC converters with high voltage gain. To obtain optimum motor performance and to reduce total harmonic distortion of the inverter output waveform, we employed sinusoidal pulse width modulation (SPWM) technique based multilevel inverter for switching of inverter power circuit. In order to maximize the power output the system components of the photovoltaic system should be optimized. Maximum power point tracking algorithm (Perturb & Observe) is used to extract maximum power from photovoltaic panel. The proposed inverter can be replaced with multilevel inverter and is implemented MATLAB/SIMULATION software for better control of motor.
