Study and simulation of Space vector PWM control of Double-Star Permanent Magnet Synchronous Generator

This paper show the unify modeling method for Space vector of Double-Star PMSG, based on the vector projection relationship, designed a two reference space vector PWM (SVM) strategy. Compared to the traditional multiphase SVM, this strategy is simple and has good control performance for unbalance double-star current which used in two independent DC bus back to back convertor system for loop current avoid, also it´s easy to extend control for treble multiphase motors. Simulation is implemented to verify the proposed two reference SVM control strategy in 0, 30, 60 shift angle for double-star Permanent Magnet Synchronous Generator (PMSG).
