A rotor which includes a plurality of permanent magnets arranged in first recesses which extend axially and are regularly distributed between a circumferential portion and a central portion of the magnetic body of the rotor, such as to define a plurality of circumferential polar sections. The magnets each comprise a first portion close to the circumferential portion, wherein the first portion is adjacent to a second portion close to the central portion, the first portion having a first rectangular radial section with a first predetermined width in a circumferential direction and the second portion having a second rectangular radial section with a second predetermined width in a circumferential direction, the second width being smaller than the first width. According to the invention, the rotor also includes a plurality of second recesses which extend axially and are each arranged between two example consecutive magnets at the second portion thereof.

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 the 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).
