A power control system includes a power inverter comprising a first side, a second side, and a plurality of power switches. The second side is configured to connect to an electric machine. A solid state fuse includes a power switch including a first terminal in communication with the first terminal of a rechargeable energy storage system (RESS) of the electric vehicle and a second terminal in communication with the first side of the power inverter. A DC-DC converter is configured to convert a first voltage output by the RESS of the electric vehicle to a second voltage. One or more sensors configured to sense one or more operating parameters of the RESS. A fuse controller is configured to receive power from the DC-DC converter, to communicate with the one or more sensors and to cause the power switch to selectively change state in response to changes in the one or more operating parameters.
