REVERSIBLE UNIVERSAL BRIDGE

摘要

A full bridge circuit is disclosed, which comprises a pair of AC terminals and a pair of DC terminals. The full bridge circuit is adapted in a first mode of operation to receive an AC voltage input at its AC terminals and provide a rectified voltage output at its DC terminals. In addition, the full bridge circuit is adapted in a second mode of operation either to receive a DC voltage input at its DC terminals and provide an AC voltage output at its AC terminals, or to receive a DC voltage input at its DC terminals and act as a bi-directional switch across the AC terminals.
