Abstract: Disclosed are a synchronous coupled boost circuit, a boost circuit, and a power supply apparatus. In the synchronous coupled boost circuit, the source of the first upper transistor is connected to the non-dotted terminal of the first winding of the coupled inductor and the drain of the first lower transistor, the drain of the first upper transistor is connected to the power output terminal; the source of the second upper transistor is connected to the non-dotted terminal of the second winding of the coupled inductor and the drain of the second lower transistor, the drain of the second upper transistor is connected to the power output terminal; the source of the first lower transistor is grounded; and the source of the second lower transistor is grounded.

Abstract: Disclosed are a DC-DC converter and a power supply device. The converter includes: a power input end; a power output end; M bridge arm circuits; a transformer component; a rectification and filtering circuit, wherein input ends of the rectification and filtering circuit are connected to secondary winding connection ends of the transformer component, and an output end of the rectification and filtering circuit is connected to the power output end. The M bridge arm circuits and the transformer component are configured to convert the input DC power supply into the required voltage on the secondary windings of the transformer component, and the required voltages are rectified and filtered by the rectification and filtering circuit, and the filtered voltage is output to the power output end, where M is greater than or equal to 3.

Abstract: The present disclosure provides a method and an apparatus for publishing product information. The present disclosure provides a method for publishing product information. Based on a stored search click log of buyers, correlation information between inquiry words and categories in the search click log is calculated. A keyword input by the seller is matched to the inquiry words. The keyword may be a word or a phrase that includes one or more words. If the keyword is matched to at least one inquiry word, at least one category corresponding to the matched inquiry word is obtained based on the correlation information. The product information is stored under one or more categories of the obtained categories. The present techniques improve the accuracy rate of recommended categories to the seller and the return rate of the published product information.
