【 摘 要 】

References(11)In this paper a new topology of high step-down dc-dc converter is proposed. The proposed converter uses an interleaved structure with one phase using a traditional buck converter and the second phase uses its inverted version. By this technique a high step down voltage conversion can be achieved as compared to the traditional interleaved buck converter. Operating principle and steady state analysis of proposed converter is given. An experiment is carried out on a 25 V input, 5 V/1 A output laboratory prototype to obtain experimental results and verify the effectiveness of the proposed converter. An efficiency of 83.7% is achieved at the rated load and a maximum efficiency of 88% is achieved at 0.5 A load current.
