ABSTRACT:
An inverting amplifier circuit generates a comparison voltage by comparing a smoothed voltage of a voltage across a semiconductor switching element and a setting voltage that is generated by device of a voltage setting volume. An operational amplifier generates a drive signal by comparing the above comparison voltage and a triangular voltage. Negative feedback is effected so that the setting voltage becomes equal to the smoothed voltage, which is inversely proportional to the rotation speed of a DC motor.
