Abstract
This invention relates to an electrical power supply circuit for an automobile vehicle.
This circuit comprises a primary stage (10) powered by a main energy source (A0, S0). This primary stage outputs an AC current to a current loop (BC) supplying power to at least one primary winding of a transformer. A converter converting AC current to direct current or voltage is associated with the secondary winding of the transformer to create an auxiliary direct current or voltage source.
