This digest introduces a new three-phase multiport AC-DC converter with integrated DC-DC conversion stages. The converter features one three-phase AC port and three DC ports: one AC port and one DC port are bidirectional, while the remaining two DC ports are unidirectional. The converter provides galvanic isolation at one DC port and a unity power factor at the AC port. All ports can be independently controlled, except for one DC port. The proposed converter topology is straightforward, using only six active switches and requiring a standard control system for operation. Additionally, when used in a microgrid, this converter can eliminate the need for two other converters, significantly reducing both the size and complexity of the system.
