要約(日本語): Recently, high step-up and high efficiency DC-DC converters are required to boost the low PV voltage to a high voltage for grid-connection. We propose a novel high step-up DC-DC converter, which has one active switch and a three-winding coupled inductor. The proposed converter based on the previous converter combines the Cockcroft-Walton circuit. This report shows the experimental results about the boost ratio of the proposed circuit in CCM (Continuous Current Mode). As a result, the proposed converter achieves high step-up with a moderate duty ratio.
