| Abstract(in English) | Many switching converters use soft-switching techniques with active-clamp snubbers in order to reduce switching surge and common-mode noise. In low-voltage and large-current DC-DC converters, synchronous-rectifier circuits are used to improve the power efficiency. Recently, it has been noticed that an abnormal phenomenon occurs under some conditions in the DC-DC converter with both active-clamp snubber circuit and synchronous-rectifier circuit. This paper describes the analysis of this abnormal phenomenon and clarifies the abnormal conditions. Furthermore, an abnormal phenomenon different from the previous one has been found experimentally. |
