【Abstract】 An optimized staircase PWM method with capability of cancelling specific harmonics and its induction motor drive system is studied by modulation and test in this paper. The modulation and experiment result,compared with that of adopting the other two PWM methods on the same drive system,has shown that the method is practicable.更多还原
