Abstract
A switched-mode power supply device including a charger connected on one side to a direct current electrical network, or rectified alternating current electrical network, a power reserve connected to a second side of the charger, and DC-DC output converters delivering regulated output voltages. The output converters are connected by an input to the first side of the charger. The charger is a current bidirectional, voltage unidirectional converter which, in a first phase, enables the power reserve to be recharged and maintained charged from the network, where the output converters are powered by the network and, in a second phase, in the presence of a power brown-out of the network, enables the power reserve to be discharged to power the output converters. A reverse blocking module is connected to the first side of the charger to disconnect the charger and the output converters from the network during the second phase.
