ABSTRACT:
A switching control signal generator generates a switching control signal which results in a soft switching operation in a small precision motor such as a brushless DC motor, without use of a separate switching noise reduction circuit, includes a circuit for supplying a linear slope value of the current supplied during a switching period of the switch using a back electromotive force for each phase and a neutral point voltage of the motor, and a circuit for adjusting a switching period by the thus supplied slope value.
