High Performance Modulation for Permanent Magnet Synchronous Motor

Man Zi-qiang

Abstract

At present,it′s always using the SVPWM for drive of PMSM,which has high ripple current and switching loss in a high-modulation and the output voltage with the given voltage is not linear relationship in over-modulation,so to find a solution to solve the above problems is of great significance.A hybrid modulation was preseuted combining the different modulation according to their characteristics to solve the above problems.Finally the feasibility of this method was verified in Matlab/Simulink.
