Abstract: An apparatus comprises a power converter circuit and a control circuit. The power converter circuit includes a primary circuit side and a secondary circuit side. The primary circuit side includes a plurality of primary switches, and the secondary circuit side includes a plurality of synchronous rectifiers and an inductor. The control circuit is configured to operate the synchronous rectifiers synchronously with the primary switches when inductor current at the inductor is greater than or equal to a reference inductor current, and operate the synchronous rectifiers in a bidirectional mode when the inductor current is less than the reference inductor current, wherein energy is delivered from the primary side to the secondary side and from the secondary side to the primary side during the bidirectional mode.
