Three-Phase Rectifiers With Current Compensation Schemes - Part II: Active and Hybrid Configurations

The current injection schemes for unidirectional three-phase diode bridge rectifiers are widely utilised in industrial and aerospace applications. The additional circuitry in combination with modern control strategies mitigate the effects of the conversion in the mains, offers acceptable dynamic and reduces size/weight for the development of compact and robust power converters. This paper is the second part of this work and it overviews the most promoted self-commutated (active) and hybrids ac-dc configurations given in literature. The operation and characteristics of these proposals are reported in this review, extending the first part that focused the analysis on passive networks.
