Wind energy based asymmetrical half bridge flyback converter for BLDC motor

The main aim of the project is to analyze the performance of an asymmetrical half bridge fly back converter under variation in wind speed. At low and high wind speeds the wind turbine are operated with the help of permanent magnet synchronous generator. It develops low amount of mechanical stress. As per wind speed the output power is also varied. The switching frequency is maintained as constant as 300Khz. The feedback controller is employed to provide speed control mechanism on permanent magnet brushless dc motor and it tend to achieve an high efficiency rating. The PWM technique is used to provide a gate signal for a 3phase inverter circuit. The BLDC motor speed may vary from 1500rpm to maximum 7000rpm. Simulation work is carried in MATLAB/simulink model.
