摘要：
An interleaved LLC converter arrangement includes two or more LLC converters for transferring power from an input side to an output side, wherein the two or more LLC converters include a first LLC converter and a second LLC converter connected in parallel on the input side and on the output side and wherein each LLC converter includes a bridge inverter at the input side. For balancing the power transfer among the LLC converters if for example the second LLC converter transfers more power from the input side to the output side than the first LLC converter, each leg of the bridge of the bridge inverter of the first LLC converter is operated with a duty cycle of 0.5 and at least one leg of the bridge of the bridge inverter of the second LLC converter is operated with a duty cycle different from 0.5.
