Title: DC/DC CONVERTER WITH FULL-BRIDGE ACTUATION
Abstract:
DC/DC converter, designed to operate in accordance with the phase-shift principle or in accordance with the LLC principle, comprising a first and a second half-bridge, which half-bridges are connected in parallel, a transformer, the primary side of which is connected between the centre points of the half-bridges, and a rectifier in connection with the secondary side of the transformer, characterized in that the half-bridges each have a series circuit comprising one switch arrangement which is connected in front of its centre point and one switch arrangement which is connected behind its centre point and each switch arrangement comprises two power-electronics switches and, in the case of both of the half-bridges, a first capacitor circuit is connected in parallel with a first of the switch arrangements and a second capacitor circuit is connected in parallel with a second of the switch arrangements, wherein the capacitor circuits each comprise at least one capacitor, and the power-electronics switches are IGBTs or MOSFETs.
