Abstract (en)
[origin: WO0179019A1] The invention concerns a power supply circuitry for motor vehicle. Said circuitry comprises a primary stage (10) fed by a main power source (A0, S0). Said primary stage delivers an alternating current to a current loop (BC) powering at least a primary winding of a transformer. A converter of alternating current into direct current or voltage is associated with the transformer secondary winding so as to constitute an auxiliary source of direct current or voltage.
