Abstract
A method for controlling a multiphase resonant DC/DC converter comprising a plurality of identical elementary resonant DC/DC converters connected in parallel. The method comprises the steps of measuring each of the supply currents (I, I, . . . I) of the elementary converters for balancing the supply currents (I, I, . . . I) and controlling switching frequencies (F, F, . . . F) of the elementary converters according to the supply currents (I, I, . . . I), so as to carry out the balancing. The supply currents (I, I, . . . I) are measured in the elementary DC/DC converters in order to balance these same currents.
