This method determines the value of a characteristic quantity (U1dc, U2dc) of a system for powering a load which comprises M DC-DC converters, connected in series to the terminals of the load and at the output of a DC current power supply, and at least one storage capacitor. This determination method comprises the measurement of a plurality of values of a first characteristic quantity (Ic) with a first high resolution, the measurement with a low resolution of a value of a second characteristic quantity (U1dc, U2dc), and a determination with a second high resolution of a value of the second characteristic quantity (U1dc, U2dc) from the plurality of values measured with the first high resolution of the first characteristic quantity (Ic) and from the value with the low resolution of the second characteristic quantity (U1dc, U2dc). The first and second high resolutions are at least 10 times greater than the low resolution.
A method for determining the value of a characteristic quantity (U1dc, U2dc) of a system (10) for powering a load (12) comprising M converter(s) (20) of a DC current into another DC current, connected in series to the terminals of the load (12) on one hand and to the output of a DC power supply (19) on the other hand, M being greater than or equal to 1, and at least one storage capacitor (22) mounted in parallel of the converter(s) (20) on the side opposite to the load (12),
A device (23) for determining a characteristic quantity (U1dc, U2dc) of a system (10) for powering a load (12) comprising M converter(s) (20) of a DC current into another DC current, connected in series to the terminals of the load (12), M being greater than or equal to 1, and at least one storage capacitor mounted in parallel of the converter(s) (20) on the side opposite to the load (12),
