Simulation and experimental models of 3-phase diode rectifier with power electronics current modulator

In this paper the structure of control system of power electronics current modulator is presented. This converter is placed in output circuit of 3-phase diode rectifier. With aid of such solution, power grid current of decribed rectifier is almost sinusoidal. Different structures of current regulator - part of control circuit - are considered. Chosen results of simulation and experimental researches are presented also.
