Digital controlled integral gain switchover method DC-DC converter

The purpose of this paper is to proposed digital controlled integral gain switchover method dc-dc converter. The integral coefficient changes for the continuous current mode(CCM) and discontinuous current mode(DCM). The integral coefficient is changed by the reactor current detection. The integral coefficient changes in the CCM using the average value of reactor current. It is confirmed that the regulation characteristics are improved. Moreover, this paper discusses the transient response of the proposed method. As a result, the transient response of proposed method shows more excellent results than the conventional methods.
