Abstract: An arc suppression pre-charge circuit includes a source for providing energy to a load and a main contactor selectively closed to provide energy from the source to the load, wherein the main contactor provides an alternate current path from the source to the load and bypasses a pre-charge branch of the circuit when the main contactor is closed. The pre-charge branch includes a voltage-controlled resistor and a control circuit configured to control a resistance of the voltage-controlled resistor.
