The invention deals with the control of a resonant LLC converter by use of control parameters. The primary current flowing in the resonant tank and a voltage at a predetermined point in the resonant tank are monitored and control parameters are set for a high side conduction interval and control parameters are set for a low side conduction interval, the control parameters for the two conduction intervals being: a peak current of the interval and a predetermined voltage of the interval. The resonant converter comprises series-arranged controllable switches to be connected to the supply source. The resonant converter is operated by setting up criteria for turning off a switch in accordance with criteria including the four control parameters. |
