Boost chopper circuit for low power wind turbine driven PM synchronous generator

Abstract

A wind generator system that employs a boost chopper and a permanent magnet synchronous generator is studied. By replacing the main circuit of generator and boost chopper with the equivalent circuit, the power and DC output voltage are obtained as a function of duty ratio of the boost chopper and generator rotational frequency. Maximum power from the generator characterized by the load and optimum duty ratio is theoretically determined. Results of Matlab/Simulink simulation are presented.
