Abstract
A control system for a voltage converter includes a first module for measuring a voltage of the DC voltage source, a module for comparing the measured voltage with a first safety threshold, and a second measurement module for measuring a speed of rotation of the rotary electric machine. A control module generates an open-circuit command which is made up of a command to open the first group of switches and a command to open the second group of switches. If a variation over time of the measured voltage of the DC voltage source is less than a first safety variation. If the speed of rotation measured by the second measurement module is less than a first safety speed.
