Conducted EMI reduction of Induction Motor Drive System by PWM switching technique

PWM 스위칭 기법에 의한 유도전동기 구동시스템의 전도노이즈 저감

Conventional SVPWM method has null switching vectors. Null switching vectors cause common-mode voltage making high in induction motor drive system. New SVPWM method without using null switching vectors are proposed in the paper. So, new SVPWM method reduces the common mode voltage for induction motor drive system. It is realized by changing software without adding hardware to induction motor drive system. Simulation results show that common-mode voltage adapting proposed method are reduced regarding conventional method.
