    摘要: A device for monitoring a life condition of a spark igniter in a gas turbine ignition system. The device includes an evaluation circuit having circuit components that include a hold capacitor, a transistor, and an operational amplifier arranged to form a sample-and-hold circuit, wherein an igniter spark impulse signal is applied to an input node of the evaluation circuit causing the transistor to turn on and the hold capacitor to discharge for a duration of the igniter spark impulse signal, and wherein a discharged voltage at the hold capacitor is maintained and output by the operational amplifier, the discharged voltage representing the duration of the igniter spark impulse and indicating the life condition of the spark igniter.

    摘要: 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.

    摘要: An aircraft piston engine magneto having a magnetic rotor and an ignition circuit with a reconfigurable charging coil inductively coupled to magnetic rotor. The charging coil includes multiple coils inductively powered by the magnetic rotor and electronically reconfigurable from a higher turn, lower amperage power coil for use when running at low speeds into a lower turn, higher amperage coil at higher speeds. The charging coil is configured into the higher turn coil by electronically connecting the multiple coils in series, and into the lower turn power coil by electronically connecting the coils in parallel. The ignition circuit is a fully electronic ignition circuit that generates and distributes ignition pulses to the piston engine spark plugs using only non-mechanically actuated electrical components within the magneto.

    摘要: An aircraft ignition system having a power circuit, a control circuit, and a discharge circuit and coupled to the spark plugs of an aircraft engine. The power circuit may include two independent power sources; e.g., alternator power (such as a permanent magnet alternator) and power from aircraft or DC power bus. The control circuit may control one or more aspects of the discharge circuit, e.g., the ignition timing. And the discharge circuit may trigger a capacitive discharge ignition event to the spark plugs.

    摘要: A solid state spark device that operates as a two terminal spark gap in a CDI exciter of an aircraft ignition system. The device includes a triggering transformer, a triggering circuit, and a control circuit. The triggering circuit is electrically connected to a first coil of the transformer and includes circuit elements connected to supply current to the first coil upon charging of the triggering circuit up to a triggering voltage. This current through the first coil of the triggering transformer induces an output in a second coil of the transformer. The control circuit is electrically connected to the second coil and includes a switch controlled by the output from the second coil. The switch, when activated by the triggering circuit, discharges energy from the exciter into an igniter of the aircraft ignition system.

    摘要: 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.
