摘要：

The purpose of this paper is to present a novel control method for the digitally controlled dc-dc converter and to improve the dynamic characteristics using the proposed simple control circuit The feature is that the derivative control in the time-domain is combined to the FER filter in the frequency-domain. As a result, it is clarified that the transient time and overshoot of the reactor current are suppressed to within 1.43ms and 1.4A and that these result is approximately 60% smaller than the conventional minimum phase FER filter method, respectively. Moreover, it is revealed that the number of parts of the digital control circuit is 15% smaller than that of the analog control circuit and the cost is also 5% smaller.
