Abstract :
The aim of this paper is to present static and dynamic analyses of digital peak current mode dc-dc converter. The current detection circuit of the proposed method consists of RC integrator and comparator as the AD converter. The proposed method can detect the peak current in real time. Analyses and the transient response of proposed method are discussed in this paper. As a result, the convergence time and undershoot are suppressed by 67% and 34% compared with the conventional digital voltage mode control method, respectively.
