Abstract
Apparatus and associated methods relate to a transformer-less way of demodulating signals generated by a synchro-resolver so as to determine a shaft angle of the synchro-resolver. A first differential output voltage between a first pair of the wye-configured secondary windings is used to generate a first output. A second differential output voltage between a second pair of the wye-configured secondary windings, different from the first pair, is used to generate a second output. The first and second outputs are combined to form a signal quadrature to the first output. The first output and the signal quadrature thereto are used to determine the shaft angle.
