Abstract
A method for operating a three-port series resonance converter (20) is described. The three-port series resonance converter (20) has a main feeding bridge (22), at least one auxiliary feeding bridge (24), and an output bridge (26). The main feeding bridge (22) is electro-magnetically coupled to the output bridge (26) via a first input coil (36) of the main feeding bridge (22), and the auxiliary feeding bridge (24) is electro-magnetically coupled to the output bridge (26) via a second input coil (46) of the auxiliary feeding bridge (24). The method comprises: sending one or more control signals to one or more switches (32, 42) of the feeding bridges (22, 24) based on a predetermined control scheme such that input voltages (V<sub>LV,m</sub>, V<sub>LV,a</sub>) applied to the feeding bridges (22, 24) are transformed to an overall output voltage (V<sub>MV</sub>) to be provided by the output bridge (26); and delaying a turn on signal for activating one of the feeding bridges (22, 24) such that transformer currents (i'<sub>p,m</sub>, i'<sub>p,a</sub>) of the feeding bridges (22, 24) reach at least approximately zero at least approximately at the same time.
