Abstract

An electrical power supply circuit for an automobile vehicle includes a primary stage powered by a main energy source. This primary stage outputs an AC current to a current loop 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.
