EN In this paper a 3-phase power diode rectifier system with quasi-sinusoidal input (power grid) current is presented. In order to benefit from it, the current modulation in a DC circuit of rectifier is used. The essential part of the current modulator is a wide-band power electronics controlled current source based on a multi-channel converter. Work of a modulator control system is based on the Generalized Sampling Expansion as an extension of the Whittaker-Kotelnikov-Shannon (WKS) sampling theory. The current modulator control algorithm respects impact of aliasing phenomena at system stability using the method proposed by one of authors. The paper includes the rectifier system description and rules of work of the current modulator. Also, some results of research on both a full rectifier simulation model and a current modulator laboratory prototype are presented.
