Relationship of Flux Harmonics and Partitioning Method of Zero Voltage Vectors

摘要

Aiming the traditional space vector PWM with equal duration of the two zero vectors, the paper introduces the principle of SVPWM. The harmonic is analyzed based on formula expression, numerical computation, and graph presentation. The optimal zero vector partitioning method is proposed. Finally, the interpolation method and discretization of the optimal method are proposed and discussed.
