摘要： A power distribution module has an input line to receive power from a DC power source. A switch selectively opens the input line and blocks supply of power from the input line to an output line to be connected to a DC load. A solid state power control controls a gate drive for the switch. The solid state power control is operable to distinguish between a pre-charge mode, at which current is rushing to supply a capacitor in the downstream DC load, and a short circuit mode, at which a short circuit exists.

摘要： A pre-charge circuit limits in-rush currents on a direct current (DC) link that includes a first DC link bus and a second DC link bus. The pre-charge circuit includes a switching device connected in series with the first DC link bus. The switching device has an ON state in which power flow is enabled on the DC link and an OFF state in which power is disabled on the DC link. A controller selectively modulates the state of the switching device to limit in-rush currents on the DC link.

摘要： An electric motor control strategy includes using a low resolution position sensor that provides a square wave output signal. The position sensor information is converted into sinusoidal commutation signals for motor control that reduces torque ripple. In one disclosed example, square wave commutation is used at low motor speeds and a controller switches to sinusoidal commutation once a selected threshold speed of the motor is reached. In another disclosed example, sinusoidal commutation is used at all motor speeds with two different techniques for converting the square wave sensor signal into a sinusoidal commutation signal, depending on the motor speed.

摘要： A capacitive element is monitored to detect at least one of a degradation level, a capacitor life expectancy, and preferably servicing alarms are generated upon detection of a critical health state. The system allows, among other things, non-hermetically sealed capacitances to be safely and cost-effectively used in weight-sensitive applications, such as in aircraft electronic systems.
