Abstract
A power system includes a power controller, an input power module for receiving AC power from a wall mains, a power driver electrically connected to the input power module to receive the AC power from the input power module, convert the AC power to low and medium voltage DC power, and selectively output the low or medium DC power under the control of power controller, and an output power module for providing DC power to a charging track with exposed electrical contacts along an upper surface. The power controller includes a microcontroller unit having software embedded therein to implement a control application that includes a main function loop, including a state machine operable to cycle through dither task states and drive states to test conditions of the power system and the track.
