要約(日本語): In this paper, the sampling method for the average current in Discontinuous Current Mode (DCM) has been proposed. In the proposed sampling method, the value of the duty at previous sampling period has been utilized to estimate the average current. At rated load, the efficiency of DCM is same as CCM at 96.7% , while at light load, the efficiency of DCM is 96.1% comparing to the efficiency 90.8% of CCM.
