Abstract

A method of operating a converter includes: charging an LC tank coupled between a switching network and a primary winding of a transformer for a first period of time by connecting the LC tank to one or more input capacitors via the switching network, where the switching network includes a first half-bridge coupled between a first supply terminal and a center node, and a second half-bridge coupled between the center node and a second supply terminal; preventing energy transfer from the primary winding of the transformer to a secondary winding of the transformer during the charging of the LC tank; and after charging the LC tank, discharging the LC tank for a second period of time by disconnecting a terminal of the LC tank from the one or more input capacitors.
