The invention relates to a systemfor controlling a voltage converter comprising a plurality of high-side switches forming a high group and a plurality of low-side switches forming a low group, the control systemcomprising:

System for controlling a voltage converter

A control system has a microcontroller () that receives a mode request (MR), a command-generating device () to supply commands and to transfer the mode request (MS) to an output pin of the microcontroller (), and a device for detecting accidental starting (), as well as a pilot () that supplies an output command signal to the switch (). The pilot () is connected to the output pin to receive the transmitted mode request (MS). The output pin is connected to an input pin of the microcontroller () to receive the transmitted mode request (MS), and the accidental starting detection device () detects when the transmitted mode request (MS) received on the input pin indicates a motor mode even though the mode request (MR) received by the microcontroller () indicates an alternator mode and, when this is the case, sends an inhibition command (INHIB_P; INHIB_T) to the pilot ().
