Three phase induction motor drive using flyback converter and PWM inverter fed from a single photovoltaic panel

摘要

The purpose of this project is to drive a three phase induction motor with the use of a single photovoltaic (PV) panel. The motor will be driven with the available power at the moment, because no battery will be implemented. In order to match the impedance of the panel (to extract the maximum power available) and boost the voltage, a fly back topology is proposed. In output of the flyback a three phase inverter is connected to drive the induction motor. This inverter will be controlled with the PWM unipolar technique. A maximum power point algorithm, the perturbation and observation, is implemented. Simulation results are provided. The panel delivered rated 210W and the motor achieved rated speed in open loop.
