This paper presents a new fast response digital PID control circuit for dc-dc converter, its dynamic characteristics and the design criterion. In the conventional digital PID control method, the sampling rate is single and the calculation process of P-I-D control is series. On the other hand, in the proposed method, the sampling rate is divided each sampling period. The calculation process of P and...
The purpose of this paper is to present a new digital model control which detects multiple output values of multiple-output dc-dc converter. In this method, the P-I-D control and the static equation model are performed. The dynamic characteristics of digital control converter are improved as compared with the conventional one.
This paper presents transient response characteristics of digitally controlled dc-dc converter with a new control method. In the conventional digital control method, the sampling rate is single and the calculation process of P-I-D control is series. On the other hand, in the proposed method, the sampling rate is multiple and the calculation process of P and I-D controls is parallel. The AD converter...
This paper presents a new auto-tuning method for the wide input voltage range digital control buck-boost dc-dc converter. This buck-boost dc-dc converter is used with wide input voltage and a suitable proportional gain and bias value are changing against the input voltage of the converter. The gain and bias value are changed suitably in real time with digital control. As simulation results, it is...
We have already reported the novel digital control method "static model reference" which is the improved smart digital reference of output voltage for its digitally controlled dc-dc converter. The circuit mechanism and the static characteristics have been cleared. This paper presents dynamic characteristics of the digitally controlled dc-dc converter with static model reference. Moreover,...
