Abstract

Abstract: As to the issue of complex trigonometric calculation for conventional SVPWM modulation algorithms, an SVPWM optimization algorithm in non-orthogonal coordinate system was proposed. By using Clark, Non-orthogonal Coordinate and per unit transformation, the algorithm simplified the regional judgment of reference vector in the sectors and triangle and optimized the calculation of basic vector action time. It realized normalization of three vectors times by using a normalization algorithm for mapping other sectors to I sector. The algorithm can effectively reduce the amount of SVPWM algorithm calculation, switching frequency, and switching losses. Simulation results show that the algorithm is effectiveness and correctness.
