Abstract Based on coordinate transformation algorithm, this paper presents a calculation of three vector time of three level SVPWM by nine sections of virtual vector saddle wave modulation. It gives details on the coordinate transformation method and the calculation process of 5 small sectors. The conclusion is the engineering practicability of this method is very high; Simulated by using the method of combining the DLL dynamic link lib and PSIM of VC++6.0, the algorithm is successfully applied in calculation of active power filter, and achieve a successful transition from theory to engineering practice.
