A method and apparatus for power conversion comprising a three-port converter comprising a DC port for coupling to an external DC line, an AC port for coupling to an external AC line, and a storage port, internal to the three-port converter, for storing excess energy and discharging needed energy during power conversion, wherein the storage port is located on a DC-side of the three-port converter and is decoupled from the DC port such that a voltage on the storage port can be controlled independently of a DC voltage on the DC port. |
