An embodiment of the present invention includes first and second electrical energy sources configured to supply current to an output, and a controller configured to receive a signal indicative of the current being drawn at the output, to compare the output current with a reference current level, and to regulate the voltage provided by the one of the first or second electrical energy sources such that: when the output current is lower than or equal to the reference current level, the first energy source supplies current equal to the output current; and, when the output current exceeds the reference current level, the first energy source supplies current equal to the reference current level and the second energy source supplies the remaining current required by the load.

Hybrid electrical power source

A high power isolated switching converter is provided, comprising a first power () stage and second power () stage connected in cascade such that the second power () stage is by-passed during part of a start-up mode.

High power switching converter

AC/DC power converter device comprising a full-wave rectifier (R) the output of which is applied to a direct current module which has two outputs: the main output is connected to the load via a capacitor (C1) which transfers a first power level (P1), and the auxiliary output is formed by a capacitor (C2) and a direct current converter (DC) which stores a second power (P2) and transfers it to the load during the full cycle of the input power wave (PE). As a result the second power level (P2) is continuously topping up the first power level (P1).
