A method for determining the regional reference voltage vector based on 60° coordinate system was proposed, and made a comparison between Cartesian and 60° coordinate systems. This algorithm could eliminate large numbers of trigonometric functions comparing to the traditional SVPWM reference vector in the course of reference vector sector determination. Just need simple addition, subtraction and comparison, it could easily get the three nearest vectors around the reference vector and reduce the on-time calculation. the results of simulation verified the correctness and fast of the proposed algorithm.
