This article discusses the design guidelines and design charts of a digital peak current mode dc-dc converter, emphasizing the analysis of its static characteristics. The relationship between key parameters is revealed and validated through experiments, demonstrating the effectiveness of the design.
The purpose of this article is to discuss the design guideline and design chart of the digital peak current mode dc-dc converter using a current-frequency conversion by analyzing its static characteristics. The operation of the proposed method is expressed by equations, and the relationships between controller parameters are derived. This discussion reveals the relationships between the peak current instruction value and the output voltage or peak current, which are necessary for designing the proposed method. Then, the design guideline and design chart are given. The validity of the static characteristic analysis is demonstrated by a prototype, whose design follows the design guideline. An appropriate operation in the steady and static state is also indicated by the experiment. As a result, the validity of the static characteristics and the design guideline of the proposed method can be verified.
