An optimized modulation technique which is specific for PWM-rectifier is proposed in this paper. It is based on the imposition of modulation frequencies different for the three rectifier legs, selected according to the power modules commutation losses. A reduction of the current harmonic content and an improvement of the overall system performances are achieved, as shown by means of an experiment implementation.

Abstract
An optimized modulation technique which is specific for PWM-rectifier is proposed in this paper. It is based on the imposition of modulation frequencies different for the three rectifier legs, selected according to the power modules commutation losses. A reduction of the current harmonic content and an improvement of the overall system performances are achieved, as shown by means of an experiment implementation.File in questo prodotto:
