Advance rectifier topology consisting of two three phase diode bridges and three thyristors is proposed in the paper for variable-speed high-power permanent-magnet synchronous generator (PMSG) wind energy conversion systems (WECSs) by using filter in addition. The recommended advanced rectifier has such as simplicity, low cost and low loss. Its feature to cascade the input voltage allows it to properly manage generator speed even when the wind velocity sink to half of the rated value. This feature is identical to a voltage boost function that cannot be found in conventional diode or thyristor rectifiers. Due to nature of a diode–thyristor rectifier, it generates harmonic currents. Also the resultant torque ripple and harmonic loss in the generators are also higher. In this we alleviated this problem by adding filters which is also verified by simulation result. Consequently, maximum power-point-tracking algorithms can be applied to optimize power capture in a wide range of wind velocities. The operating principle of the rectifier is elaborated. Its use and control in the WECS is presented.
