A Universal Power Converter For Emergency Charging Of Electric Vehicle Batteries, Norman R. Cox
Electrical and Computer Engineering Faculty Research & Creative Works
An on-board electric vehicle battery charger capable of accepting AC or DC inputs in the range of 12 to 260 volts is described. The charger provides near-unity power factor and high efficiency for routine charging from AC sources, but can also be used to tap other sources of power in the event of an emergency.

Current-regulated brushless DC machines are used in a wide variety of applications including robotics, actuators, electric vehicles, and ship propulsion systems. When conducting system analysis of this or any other type of drive, average-value reduced-order models are invaluable since they provide a means of rapidly predicting the electromechanical dynamics and are readily linearized for control system synthesis. In this paper, a highly accurate average-value reduced-order model of a hysteresis current-regulated brushless DC drive is set forth. In so doing it is demonstrated that the drive exhibits five distinct operating modes. The physical cause of each of these modes is explained …
