A dongle for connecting a computerized device to a certified unit under test (UUT) includes a computerized device communication port and a UUT communication port. The dongle also includes a communication module operatively connecting the computerized device communication port and the UUT communication port. The communication module includes an internet protocol (IP) module that supplies an IP address to a computerized device connected to the computerized device communication port, wherein the IP address enables the computerized device to receive signals from and/or send signals to the UUT.

A system balances current flowing through a solid-state power controller system including at least two output channels connected in parallel. The system delivers a first current to a load via a first output channel to a load, and delivers a second current to the load via a second output channel connected in parallel with the first output channel. The system further determines a first strength of the first current and a second strength of the second current, and adjusts at least one of a first resistance of the first output channel and a second resistance of the second output channel such that the first current strength is substantially equal to the second current strength.

Multi-channel current balancing system including parallel solid-state power controllers

Embodiments are directed to a transient protection circuit configured for use in a SSPC having a plurality of power channels. The transient protection circuit includes a shared transient voltage suppressor, and a shared protection line communicatively coupled to the shared transient voltage suppressor. The shared protection line is configured to be communicatively coupled to and shared by the plurality of power channels. When the shared protection line is communicatively coupled to and shared by the plurality of power channels, energy above a threshold on any one of the plurality of power channels is dissipated through the shared protection line and the shared transient voltage suppressor.

A circuit comprises an alternating current (AC) feed line, a solid state power controller portion connected to the AC feed line, a load connected to the solid state power controller portion, a positive clamp rail, a negative clamp rail, a ground, a first diode connected to the AC feed line and the positive clamp rail, a second diode connected to the AC feed line and the negative clamp rail, a third diode connected to the load and the positive clamp rail, a fourth diode connected to the load and the negative clamp rail, a fifth diode connected to the positive clamp rail and the ground, a sixth diode connected to the negative clamp rail and the ground, and a capacitor connected to the positive clamp rail and the negative clamp rail.

A light emitting diode (LED) control system may include a LED control system for an aircraft. The LED control system may include an LED power controller, and a solid state power controller (SSPC) that includes a processor in communication with the LED power controller, where the LED power controller and the solid state power controller are integrated onto a single power module. The LED control system is configured to receive DC power from a power source, determine, via the processor, current flow through a series MOSFET element connecting to at least one LED, to control operational voltage across the at least one LED, and adjust, via the processor, a gate voltage of the series MOSFET element with the LED power controller.

Solid state power controller for aerospace LED systems

A power generation system has a generator, a power bus and an electrical accumulator unit. The electrical accumulator unit includes an independent controller that actively filters transients from the power bus.

Active filtering electrical accumulator unit

A power system has a generator, a variable load, and an electrical accumulator unit. The electrical accumulator unit stores power when the generator generates excess power, and supplements power from the generator when the generator generates insufficient power.

Method for controlling an electric accumulator unit

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.

SSPC with active current limiting

A method and apparatus for controlling a converter circuit within the electrical accumulator unit based on a comparison between an actual average converter current and a desired average converter current.
