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).
