According to the towel rack, the structure that the main rack body and the towel rack body which are independent of each other are inserted and then clamped is utilized, so that the towel rack is installed on the main rack body, auxiliary parts are not needed in the assembly structure, and therefore the technical problems existing in the prior art are solved.

Method for reducing high-temperature voltage stress of SiC module through Bin division

The invention discloses a method for reducing high-temperature voltage stress of SiC modules through Bin division, and the method comprises the steps: S1, testing samples of a plurality of SiC modules through double pulses, so as to obtain voltage stress data test results of different samples at high temperature; s2, a plurality of factors influencing the voltage stress of the SiC module at the high temperature are subjected to statistical analysis according to the obtained voltage stress data test result, so that influence relation data of different factors on the voltage stress at the high temperature are obtained; s3, key parameters are selected from the multiple factors, and Bin division is carried out on the key parameters. According to the method for reducing the high-temperature voltage stress of the SiC module through Bin division, the voltage stress of the SiC module at the high temperature can be effectively reduced under the condition that the current capacity is not lost, and ...
