| 20100277960 | AIRCRAFT POWER SUPPLY AND METHOD OF OPERATING THE SAME - An aircraft power supply for providing DC power with improved power quality characteristics. The aircraft power supply includes a transformer control system that can use closed-loop feedback from a DC power output to control switches that can short primary windings turns of a step-down transformer. By shorting turns in the primary, the transformer control system can control or manipulate the turns ratio in the transformer and compensate for decreases in the DC power output. | 11-04-2010 |
| 20100171365 | AIRCRAFT POWER SUPPLY AND METHOD OF OPERATING THE SAME - An aircraft power supply for providing DC power with improved power quality characteristics to the aircraft. According to one embodiment, the aircraft power supply includes an input filter, a step-down transformer, one or more rectifier networks, and an output filter with a voltage modulation attenuator to passively improve power quality characteristics. The voltage modulation attenuator may use a certain arrangement of inductors, capacitors and diodes to reduce voltage transients in the aircraft power supply. | 07-08-2010 |
| 20090050931 | SWITCHING ASSEMBLY FOR AN AIRCRAFT IGNITION SYSTEM - A switching assembly is disclosed for a high voltage aircraft ignition system. The switching assembly includes a ceramic substrate and switch die that includes an anode bonded to an electrical pad on the ceramic substrate. The switch die includes a semiconductor device having a plurality of interleaved gates and cathodes, and includes a ceramic cap having at least one gate pad connected to the gates and at least one cathode pad connected to the cathodes. The switching assembly includes leads connected to the gate pad, the cathode pad, and the electrical pad on the substrate. The switch die and a portion of the leads are potted to form the completed assembly. | 02-26-2009 |
| 20080238191 | POWER SUPPLY UNIT FOR USE WITH AN AIRCRAFT ELECTRICAL SYSTEM - A power supply unit that provides uninterrupted power to an aircraft power bus during switchovers of the aircraft bus from one power source to another. The power supply unit includes circuitry to distinguish between loss of bus power due to switchovers between power sources and loss of bus power due to shutdown of the aircraft. The power supply unit includes a low voltage lockout circuit to interrupt the supply of power when the aircraft bus voltage falls below a minimum value. | 10-02-2008 |
