Abstract
With the advent of fast power devices, the high dv/dt voltage produced by PWM inverts have been found to cause EMI noise, shaft voltage and bearing current. This paper describes the application of newly developed Conducted EMI reduction SVPWM technique in induction motor drives. The newly developed common mode voltage reduction SVPWM technique don't use any zero-vector states for inverter control, hence it can restrict the common mode voltage more than conventional PWM technique. The validity of the proposed technique by software approach is verified through simulation and experimental results.
