A multistage power supply system and method for providing uninterrupted low voltage electrical power to control circuitry in an electric or hybrid-electric vehicle. A first stage includes a converter for receiving a low voltage input from a vehicle battery and converting the vehicle battery low voltage input to a high voltage output. A second stage provided in series communication with the first stage includes a converter for receiving one of a rectified AC high voltage input and the first stage high voltage output and converting the one of the rectified AC high voltage input and the first stage high voltage output to a low voltage output for use in powering the vehicle control circuitry. The low voltage output is produced by the second stage from the rectified AC high voltage input when the rectified AC high voltage input is present, and the low voltage output is produced by the second stage from the first stage high voltage output when the rectified AC high voltage input is absent.
