A smart approach for design of digitally controlled multiple-output dc-dc converter

This paper presents a smart approach for digital control forward type multiple-output dc-dc converter. In this case, the central problem of design is how to decide the integral coefficient. Since the decision of integral coefficient depends on the static characteristics, the selected integral coefficient is not suitable to perform the superior dynamic characteristics. Then, it is important to set the suitable the integral coefficient for not only static characteristics but also dynamic characteristics. As a result, in the proposed design approach, the convergence time of the output voltage and the overshoot of reactor current are improved 20% and 11%.
