Three port converter with dual independent maximum power point tracking and dual operating modes

摘要

A method and apparatus for a three port converter with independent dual input comprising: a first DC port for coupling a first half-bridge circuit of the three-port converter to a first external DC line, a second DC port for coupling a second half-bridge circuit of the three-port converter to a second external DC line, wherein the second half-bridge circuit is decoupled from the first half-bridge circuit, and an AC port for coupling to an external AC line, wherein (i) the first half-bridge circuit and the second half-bridge circuit are operated as a full H-bridge during a full-bridge operating mode, and (ii) the first half-bridge circuit or the second half-bridge circuit is operated as a half H-bridge during a half-bridge operating mode.
