  • Resolver excitation using threshold band of voltages
    Patent number: 11566919
    Abstract: A device for excitation of a resolver comprising an excitation coil and one or more sensing coils includes circuitry. The circuitry is configured to amplify a carrier signal using a first gain value to generate an excitation signal for output to the excitation coil of the resolver and determine whether the excitation signal is outside of a threshold band of voltages. The circuitry is further configured to amplify the carrier signal using a second gain value, wherein the second gain value is generated based on whether the excitation signal is outside of the threshold band of voltages.
