  • +28V aircraft transient suppression
    Patent number: 8159808
    Abstract: An apparatus and method for suppressing voltage fluctuations across a relay coil is disclosed. The method includes the steps of monitoring a voltage drop across a relay coil by a difference amplifier; providing an output of a reference source and an output of the difference amplifier to an integrator amplifier; providing an output of the integrator amplifier to a transistor; and driving the relay coil by controlling an output of the transistor based on the output of the integrator amplifier, wherein the output of the reference source is selectively applied to the integrator amplifier in response to a monitored undesired voltage fluctuations across the relay coil.
