ABSTRACT:
An amplitude regulation circuit which includes a maximum detection circuit which outputs a maximum signal MAX that is distorted to some extent during and around a time when a highest-level signal switches between signals V1, V2, and V3. The amplitude regulation circuit also includes a minimum detection circuit which outputs a minimum signal MIN that is distorted to some extent during and around a time when a lowest-level signal switches between signals V1, V2, and V3. Such distortions reduce variations in amplitude detection signal AMP that represents a difference between MAX and MIN. The amplitude regulation circuit amplifies rotor position signals H1to H3based on amplitude detection signal AMP according to AGC, thereby maintaining amplitudes of signals V1to V3constant while maintaining sinusoidal waveforms.
