Claims (1)

양,음방향의 삼각파를 발생하되 그중 어느 하나는 반주기만큼 쉬프트(Shift)시켜 출력하는 삼각파 발생수단; 콘트롤 입력신호와 궤한신호의 차이에 비례하는 신호를 입력으로 하여 상기 삼각파 발생수단에서 출력되는 양,음방향의 삼각파 신호레벨과 비교하는 비교수단; 그리고 상기 비교수단에서 출력되는 신호에 따라 모터를 정,역전 구동하는 모터 드라이브단으로 이루어짐을 특징으로 하는 DC모터 드라이브회로.Triangular wave generating means for generating positive and negative triangular waves and shifting one of them by a half period; Comparison means for inputting a signal proportional to a difference between a control input signal and a feedback signal and comparing the signal with the positive and negative triangle wave signals output from the triangle wave generator; And a motor drive stage for driving the motor forward and reverse according to the signal output from the comparing means. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
