A Review of AC-DC Converters with Injection Circuits - Part II

AC-DC three-phase converters are very well known for having enhanced power quality with unity displacement power factor, low total harmonic pollution in the AC side, and controllable DC output with unidirectional or bidirectional power flow. The second part of this paper presents a review of several three-phase AC-DC converters with active current injection circuits, including some hybrid configurations, detailing their respective topologies and characteristics.
