Abstract
An interface circuit for detecting a fault in a resolver is provided. More specifically, the interface circuit includes the resolver connected to an intermediate point of a stator coil of a first output terminal for a sine wave signal and an intermediate point of the stator coil of a second output terminal for a cosine wave signal to output the sine and cosine wave signals as a common mode signal. Also includes is resolver fault detection interface unit that adjusts a gain and an offset of the sine wave signal and the cosine wave signal in order to adjust the sine wave signal and the cosine wave signal received as a common mode signal to a frequency that can be suitably applied to an analog/digital terminal of a microcomputer, and to allow high-frequency components of the sine wave signal and the cosine wave signal to pass therethrough.
