Abstract (en)
[origin: WO2014174171A1] The control method according to the invention concerns a multiphase resonant DC/DC converter comprising a plurality of identical elementary DC/DC converters connected in parallel. Supply currents (IR1, IR2,…IRn) are measured in the elementary DC/DC converters in order to balance these same currents. According to the method, switching frequencies of the elementary DC/DC converters are controlled on the basis of the supply currents in such a way as to achieve said balance. Another feature involves setting the supply currents to a common reference intensity (Iref) determined on the basis of a difference between an output voltage (Vo) of the multiphase converter and a nominal voltage (Vref).
