This motor driving control apparatus has (A) an inverter unit configured to drive a motor; (B) a separation switch configured to separate a power source from the inverter unit; and (C) a controller configured to instruct the separation switch to separate the power source from the inverter unit and control the inverter unit to perform switching according to a speed and a braking target torque, upon detecting an event that braking should be performed without passing a regenerative current to the power source from the inverter unit. By introducing the separation switch that operates as described above, it becomes possible to perform control so as to consume the power by the motor itself without passing the regenerative current to the power source such as a battery.

A circuit arrangement supplies an electrical vehicle component part of a motor vehicle with an operating voltage, which has a voltage value that is greater than a predetermined limit value for dangerous contact. The circuit arrangement has a source circuit for generating the operating voltage and two line elements for transmitting the operating voltage to the vehicle component part. A reference contact is provided for connecting the circuit arrangement to a reference-ground potential. The source circuit is configured, in order to generate the operating voltage, to generate a first component voltage between the first line element and the reference contact and a second component voltage between the second line element and the reference contact.
