The purpose of this paper is to present a model control method without a current detection. In the proposed method, output current is predicted from the duty ratio and the output voltage in order to exclude the sensing resistor. Only the output voltage and input voltage are detected. The bias value of the P-I-D control is changed using the predicted output(More)
This paper presents the digital control method for the wide transient range dc-dc converter. We have already reported that an exponential function model is effective in improvement of transient characteristic. There is a problem that calculation time is long by using the exponential function and the square root. In this paper, those functions are(More)
