A DC-DC converter includes a bridge circuit, a resonant tank circuit coupled to an output of the bridge circuit; a rectifier circuit having an input coupled to the resonant tank circuit and an output, and an output filter coupled to the output of the rectifier circuit. A controller is coupled to the bridge circuit, the resonant tank circuit and the output of the DC-DC converter. The controller is configured to control a switching frequency of the bridge circuit to operate the DC-DC converter as a boost converter and a buck converter. When the DC-DC converter is operating as a buck converter, the controller controls the rectifier circuit to selectively block energy transfer from the rectifier circuit to the converter output based upon an output current of the DC-DC converter being greater than current demand thereof, thereby reducing output current of the DC-DC converter and extending an operating range thereof.

An electrical system includes an input node electrically connectable to a power supply. The system includes a plurality of voltage suppressors, with at least one of the voltage suppressors electrically connected to the input node. A voltage selection switch is electrically connected to at least one of the plurality of voltage suppressors. A controller in communication with the switch may selectively operate the switch based on a nominal operating voltage at the input node.

A sensor interface circuit for a vehicle includes a signal conditioning module having at least one raw sensor signal input, and at least one conditioned sensor signal output, and a differential comparator module including a differential comparator and an adaptable hysteresis module. The adaptable hysteresis module provides a first hysteresis magnitude to the differential comparator when a sensor signal is below a threshold and a second hysteresis magnitude to the differential comparator when the sensor signal is above the threshold.
