Abstract: A method, using multiple position sensors, for determining a characteristic of the actuator or a system, wherein the characteristic is causing or is indicative of the cause of the change in position of the actuator. One characteristic may be the lost motion of the actuator or system. Lost motion is the lag between the motion of a controlled device and that of an electrical drive device due to yielding or looseness. The lost motion of an actuator may increase as components wear and may eventually degrade the function or cause failure of the actuator and/or system.

Abstract: A direct current (DC) fast charger for charging batteries of electric vehicles (EVs) including a primary circuit, having nine switches, electrically linked to primary wires of a transformer and configured to receive three-phase alternating current (AC) power and increase the frequency of the AC power; and a secondary circuit, including six switches or diodes arranged to rectify AC voltage into DC power, that is electrically linked to a secondary wire of the transformer.
