1. A motor control processing unit for a motor control device having a low-voltage source inverter unit, the motor control processing unit configured to control the low-voltage source inverter unit to provide a low voltage to a low-voltage motor by using a pulse-width modulation (PWM) scheme, characterized in that:
the motor control processing unit is configured to control the low-voltage source inverter unit according to a flat PWM scheme, which comprises a flat-bottom or flat-top PWM scheme, at least at some times; and
the motor control processing unit is configured to activate and/or deactivate the flat PWM scheme in dependence upon a parameter representing an operating condition, the parameter including one or more of a measured temperature, a torque setpoint or a power setpoint.
