US 2015/0029758 A1 · WIDE INPUT DC/DC RESONANT CONVERTER TO CONTROL REACTIVE POWER

Abstract

A DC/DC resonant converter system includes a primary converter unit having a split resonant tank circuit. The resonant converter unit further includes a plurality of primary switching units that control the current flowing into the split resonant tank circuit. A controlled secondary rectifier unit includes a plurality of rectifier switching units to reduce reactive power in the primary converter unit. A phase-shift controller is in electrical communication with the primary converter unit and the controlled secondary rectifier unit. The phase-shift controller is configured to determine a rectifier phase-shift angle based on the plurality of primary switching units and to control switching of the plurality of rectifier switching units based on the rectifier phase-shift angle.
