Abstract :
This paper presents a new hybrid rectifier composed by the parallel association of a single-switch three-phase boost rectifier with a PWM three-phase unidirectional rectifier. According to this proposal, each rectifier processes about a half of the output rated power. Thus, it allows to improve the robustness and to provide a high efficiency to the system. The hybrid rectifier is capable of providing output voltage regulation and power factor correction. An overview of some high power rectifier topologies and the mathematical analysis, the control scheme and the simulation results of the proposed hybrid rectifier are also presented in this paper
