Abstract
A system performs a method for operating a vehicle. A cable is attached between an inverter of the vehicle and a motor of the vehicle, the cable having a resistance. The inverter is operated using a first direct current (DC) reference voltage. A processor obtains a current from the motor, calculates a power factor at the inverter, obtains a resistance of the cable, determines a voltage drop between the inverter and the motor from the current, the resistance and the power factor due to a presence of the cable, determines a DC compensation voltage from the voltage drop, and adjusts the first DC reference voltage to a second DC reference voltage using the DC compensation voltage.
