VOLTAGE CONVERTER ON BOARD A MOTOR VEHICLE AND ASSOCIATED ELECTRIC CHARGER

The invention relates to a voltage converter (200) on board a motor vehicle, for converting a first voltage into a second voltage different from the first voltage, comprising: - a plurality of cells (C), each comprising an arm of transistors (T3, T4) controlled as a chopper to generate the second vo...

Beschreibung
Zusammenfassung:	The invention relates to a voltage converter (200) on board a motor vehicle, for converting a first voltage into a second voltage different from the first voltage, comprising: - a plurality of cells (C), each comprising an arm of transistors (T3, T4) controlled as a chopper to generate the second voltage; - at least one isolation transistor (K3-R); and - a circuit (210) for controlling the transistors, the control circuit (210) being configured to be able to selectively keep said at least one isolation transistor (K3-R) open so as to decouple a cell of the plurality of cells and to use the arm (K5, K6) of said cell to supply a third output voltage.
