Design Criterion of Digitally Controlled Multiple-output Dc-dc Converter

The last few years, a considerable number of studies have been made on a digital control. One reason is that this technique will lead to a future energy management and system integration. At a first step, it may be helpful to begin with a study of the design criterion of the digital control. Although studies have been made on the digital unique characteristics, there is little agreement on the total design criterion. This paper presents a digital criterion for the forward type multiple-output dc-dc converter. In this case, the central problem of design criterion is the relationship between the digital control parameter and the number of bits of the calculation part of the digital control circuit.
