Power factor correction (PFC) rectifiers are essential for load side harmonic and reactive power correction. In recent years, research and applications of PFC rectifiers have attracted more attention due to the increased energy awareness in the global. In this paper, a simple digital controlled three-phase six-switch H-bridge boost rectifier is proposed. The control objective is to operate the rectifier...
A new tendency in development of power supplies is power factor corrected (PFC) rectifiers which can work without harmonic pollution to source. The former literatures propose a new one-cycle controlled three-phase boost PFC rectifier which has many advantages. But the rectifier is analog based and difficult to control input currents flexibly under unbalanced source. This paper improves the control...

One cycle control three-phase boost rectifier proposed in literature has many advantages. By modifying the main topology, it has capability of controlling three-phase PFCs, APFs, STATCOMs, and grid connected inverters. But under unbalanced source, it is difficult to control input currents flexibly in case of keeping constant input power, keeping balanced input currents, or keeping the input currents...
In this paper, a new three-phase input, three-phase four-wire output, and with a high-frequency AC link matrix type convertor is discussed. The topology of the conventional matrix convertor is modified with an additional high-frequency transformer for three-phase four-wire electronic power distribution application. The proposed approach accomplishes high output voltage transfer ratio which is more...
