A power supply system and a control circuit for a power supply system are provided. The power supply system includes a first battery, a second battery, a first switch and a second switch are operable to control power supply from the first and second battery by turning on and off. The control circuit includes a third switch. A drain of the third switch is connected to the gates of the first and second switches and a source of the third switch is connected to the source of the first and the second switches. In the event of a ground fault, a voltage at the gate and source of the third switch is the same, turning on the third switch voltage wherein a voltage at the gates and sources of the first and second switches are made equal, turning off the first and second switches.
