PROBLEM TO BE SOLVED: To acquire a digital angle output signal easily via a feedback loop from a three-phase synchro signal without using a Scott transformer. ! SOLUTION: The digital conversion method and device of synchro signal are a method and device for converting a three-phase synchro signal (S1-S3) into a digital angle output signal (φ) by an S/D converter (3), in which the three-phase synchro signal (S1-S3) is inputted to the S/D converter (3) without using the Scott transformer, and based on a feedback loop (22) based on the digital angle output signal (φ), control deviation (ε) is made zero. !
