Abstract :
T This paper presents an auto-tuning digital control for buck-boost dc-dc converter to improve the dynamic characteristics. Furthermore, the relationship among the control parameters, the regulation characteristics and the dynamic characteristics is discussed. In addition, the feedforward control against the input voltage is added to the proposed auto-tuning method. As a result, it is clarified that the proposed auto-tuning method with the feedforward control is useful to the buck-boost dc-dc converter.
