Low-cost resolver-to-DC converter

A simple technique for implementation of resolver-to-DC converter is presented in this paper. The obtained output in form of DC voltage is linearly proportional to the position of motor shaft angle. The configuration of proposed converter consists of commercial available circuit building blocks such as demodulator, sine-to-triangular wave converter, logic control, and triangular-to-sawtooth converter. The proposed approach is obtained the economical attraction. Experimental results confirming the circuit performance are agreed with the expected values.
