Abstract
An electromechanical motor vehicle power steering mechanism may include an electric motor and a control unit. The electric motor may be configured to provide a steering assist force. The control unit may be configured to control a current to the electric motor. Further, the control unit may include two redundant power supply units. Each of the two redundant power supply units may be connected to a vehicle battery. Also, the two power supply units may each comprise a primary winding and a secondary winding as part of a flyback transformer with a shared iron core. The shared magnetic core may be E-shaped with a middle leg and two side legs. The primary winding and the secondary winding of one of the two redundant power supply units may be wound around a first of the two side legs.
