Abstract

Electronic control unit (18AVG, 18AVD) of an electric motor (14AVG, 14AVD) comprising a number N of phases, forming an electric actuator of an electromechanical brake (16AVG, 16AVD) of a vehicle. This control unit (18AVG, 18AVD) comprises first (20) and second (22) inverter cells intended to each supply at least part of the N phases. The first (20) and second (22) inverter cells are supplied respectively by first (24) and second (26) sources delivering DC voltages of different values ​​respectively. The first (20) inverter cell is provided with a DC voltage converter (20C) converting the voltage to bring it to the value of the supply voltage of the second (22) inverter cell.
