Abstract
A resolver excitation apparatus that adjusts amplitude of a sinusoidal excitation source signal to generate an excitation signal having predetermined amplitude in order to excite an exciting winding of a resolver. A parallel resonant circuit having a parallel resonant element that functions as parallel resonant impedance for impedance of the excitation winding. A series resonant circuit having a series resonant element that functions as series resonant impedance for the impedance of the excitation winding.
