    Abstract :

    This Paper mainly focusing on the utilization of renewable energy i.e., solar energy to drive the induction motor. Since to reduce burden on conventional energy sources there is need to move towards solar energy to supply power to electrical loads. Solar power generation is a clean and pollution free power generation and it is inexhaustible power generation too. In this paper, simulations of solar photovoltaic system fed induction motor is presented and analyzed briefly. In addition to this, controlling of solar photovoltaic system with fast digital controller i.e. FPGA has also been presented. An MPPT charge controller is used in solar energy harvesting applications to extracts the maximum power from an ambient solar energy source even under variations in light intensity and temperature. Initial stage FPGA controlled charge controller provides constant DC power at its output terminals and it is converted into AC by using FPGA controlled 3- level diode clamped inverter. In this paper open circuit voltage mode FPGA controlled MPPT charge controller is designed to get constant DC power from solar PV module. This DC power is act as a source to FPGA controlled 3-Level inverter; and converts into AC power by this inverter. Sinusoidal Pulse Width Modulation (SPWM) is implemented in Xilinx system generator environment and MATLAB to control the inverter. This inverter output is used to feed the induction motor. THDs of voltages and currents of 3-level inverter and induction motor are also observed
