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), 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), and the main feeding bridge (22) and the auxiliary feeding bridge (24) are configured such that their resonance frequencies are at least approximately the same. 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); sending a turn off signal to at least some of the switches (32, 42) of at least one of the feeding bridges (22, 24) such that an output voltage (v'<sub>p,m</sub>, v'<sub>p,a</sub>) of the corresponding feeding bridge (22, 24) is floating, once an output bridge current of the output bridge (26) is at least approximately zero.
