US 2022/0069700 A1 · Bidirectional Multiple-Port Power Conversion System and Method

Abstract

A bidirectional power conversion system includes three power conversion ports. A first power conversion port includes a power factor correction device and a primary power conversion network. A second power conversion port includes a plurality of switches and a plurality of diodes, wherein an output voltage of the second power conversion port is regulated through adjusting an output voltage of the power factor correction device as well as through adjusting an operating parameter of the primary power conversion network. A third power conversion port includes a first switch network and a power regulator connected in cascade, wherein the first power conversion port, the second power conversion port and the third power conversion port are magnetically coupled to each other through a transformer.

Dependent claims

1-20. (canceled)

A method comprising:

transferring energy in a bidirectional multiple-port power conversion system having a first port configured to be coupled to an AC element, a second port configured to be coupled to a first DC element, and a third port configured to be coupled to a second DC element;
and
configuring the bidirectional multiple-port power conversion system as an AC/DC power conversion system in response to an AC power source coupled to the first port, and configuring the bidirectional multiple-port power conversion system as a DC/DC power conversion system or a DC/AC power conversion system in response to disconnecting the AC power source from the first port.

Dependencies are inferred from the claim text.
