Abstract
A converter circuit to be connected to an electrical energy source includes a chopper circuit having an input terminal capable of being connected to said electrical energy source, a first output circuit adapted to being connected via a first switch to an output terminal of the chopper circuit, a second output circuit adapted to being connected via a second switch to the output terminal of the chopper circuit, and a control circuit. The control circuit is adapted for controlling the duty cycle of the chopper circuit as a function of the variation in voltage of said electrical energy source, and switching between the first and second switches as a function of a range of output voltage settings for the first output circuit.
