Research of SVPWM algorithm based on 120 degree coordinates system

In order to avoid the problems of structure complexity and complicated computation of traditional algorithm, a new space vector pulse width modulation algorithm based on 120 degree coordinates is put forward. The coordinates of voltage space vector in 120 degree is obtained with this algorithm through coordinate transformation. By simple four arithmetic operations and logical judgments, the section of voltage space vector and the operating time of the basic vectors can be obtained quickly and accurately. The results of simulation and experiment indicate that the new SVPWM algorithm has the advantages of simple structure, short operational cycle and small memory occupation, which can effectively reduce the requirements of computational performance of the controller when using SVPWM algorithm.
