The purpose of this paper is to present a new digital control method of the forward type multiple-output dc-dc converter with both the P-I-D control and the static equation model. The dynamic characteristics of digital control dc-dc converter are improved as compared with the conventional one. As a result, it is seen that the forward type multiple-output dc-dc converter with a new digital control has a superior transient response compared with that of the conventional control. The overshoot of reactor current is improved 28%.
