SYSTEM FOR POWERING AN ELECTRIC MACHINE
First Claim
1. A system for supplying power to an electric machine comprising:
- a voltage source;
an electronic circuit for supplying power to said electric machine;
a first switch, wherein the voltage source supplies power to said electronic circuit when said first switch is in the closed position;
at least one capacitor mounted in parallel on said voltage source when said first switch is in the closed position;
a circuit for precharging said capacitor; and
a second switch, wherein the precharge circuit is connected to said voltage source when said second switch is closed, and wherein said first switch is controlled to close after the precharging of said at least one capacitor.

Abstract
The invention relates to a system (100) for powering an electric machine (M). One particularly interesting application of the present invention is to the field of powering electric motors used in automobiles. The system (100) comprises a voltage source (102), an electronic circuit (108) for supplying the electric machine (M), a first switch (101), wherein the voltage source (102) powers the electronic circuit (108) when the first switch (101) is in a closed position, at least one capacitor (104, 105) mounted in parallel on the voltage source (102) when the first switch (101) is in the closed position, and a precharge circuit (114) for the capacitor (104, 105). The system further includes a second switch (+APC), wherein the precharge circuit (114) is connected to the voltage source (102) when the second switch (+APC) is closed, and the first switch (101) is controlled so as to be closed after the precharge of the capacitor (104, 105).
