Abstract

Disclosed is a multi-phase coupled-LLC, CLLC, resonant converter, and controller therefor, the converter having a plurality of primary-side LLC circuits, each comprising a series-arrangement of a capacitance and two inductances between a respective input and a common node, wherein each input is switchable between a first supply voltage level and a second supply voltage level, the controller comprising: a hysteretic controller; and a finite state machine; wherein the hysteretic controller is configured to trigger a change of state of the FSM in response to a voltage level of a resonant capacitor of a one of the LLC circuits crossing a trigger voltage level; and wherein the FSM is configured to change between a plurality of states, wherein each state corresponds to a different combination of states for each of the LLC circuits of the multiphase CLLC. Corresponding methods are also disclosed.
