PURPOSE:To detect voltage at high precision also in case of low frequency and control a motor at high precision, by detecting the terminal voltage of the motor without using a transformer. CONSTITUTION:By correcting circuits 16-18, the output of time lag circuits 13-15 is corrected, and the output o...
