METHOD FOR CONTROLLING A DC-DC CONVERTER IN A MOTOR VEHICLE ELECTRICAL SYSTEM

Disclosed is a method for controlling a DC current converter present in an on-board network of a motor vehicle including a service battery, the on-board network being connected, via the converter, to a traction battery that supplies power to a traction network with inverter and electric machine. When a transmission of power transients from the on-board network to the traction network leading to instabilities in the traction network is detected, an auxiliary mode of control of the converter is implemented with a limit on the current output from the converter depending on a state of charge of the service battery, the current limit increasing as the charge of the service battery decreases.
