RESOLVER INTEGRAL DEMODULATION USING ZERO CROSSING POINTS

Examples described herein provide a method that includes storing, in a first buffer associated with a first ADC of a DSP, resolver sine values collected from first, second, and third resolvers. The method further includes storing, in a second buffer associated with a second ADC of the DSP, resolver cosine values collected from the first, second, and third resolvers. The method further includes storing, in a third buffer associated with a third ADC of the DSP, resolver excitation values collected from the first, second, and third resolvers. The method further includes determining a midpoint value of the resolver excitation values, determining a sine amplitude based at least in part on the resolver sine values and the midpoint value, and determining a cosine amplitude based at least in part on the resolver sine values and the midpoint value. The method further includes identifying a quadrant of a resolver position.
