Abstract

Digital methods of modulation in pulse converters for EMC providing and electrical energy quality guarantee are considered. By reproducing a digital modulation, it is possible to realize algorithms of operation differing from those in analogue modulators. It´s suggested to co-ordinate the discrete-time transient responses of converters with input discrete-time digital signal by the criteria based on minimization of overshoots.
