摘要： An electromagnetic contactor assembly with a sensing circuit for determining contactor state based upon the reluctance of the contactor coil. The coil has an electromagnetic coil and a movable contact separated from the coil by a gap when the coil is not energized. Energizing the coil causes the movable contact to close the gap and contact the coil. The determination of the relationship between the reluctance in the coil when the gap is in an open and closed state allows contactor gap status to be measured by measuring the coil inductance. A sensing circuit is added to the drive circuit to measure changes in AC current during the pulse cycle which holds the contacts in this closed position. The sensing circuit measures the AC current and is able to signal contactor status based on that value.

摘要： In a delta-connected power supply system, phase switching circuits are employed and are activated during the failure of one of N+1 converter units. This activation is employed even though there has been no outage in any one of the input phases. The result is two operating converters running in effect as three-phase converters. Since each of the converters then acts as a full wave three-phase bridge with a resistor load, the line currents are perfectly balanced although unity power factor is not maintained during this non-normal mode of operation. In such circumstances, higher power factor is temporarily sacrificed to achieve continuous operation and therefore higher overall system reliability.

摘要： Disclosed is a circuit for preventing damage to a controllable switching circuit as a result of a reverse recovery current originating from a rectifier circuit coupled to the controllable switching element during recovery of the rectifier circuit. The damage prevention circuit includes a reactive impedance circuit coupled in parallel with the rectifier circuit for controlling a reverse recovery current from the rectifier circuit during recovery of the rectifier circuit. A second controllable switching element is employed to direct the reverse recovery current to the reactive impedance circuit in response to recovery of the rectifier. The second controllable switch also directs the reverse recovery current from the reactive impedance circuit to a load, wherein the reverse recovery current may be safely diminished.
