Link to SEMISEL: http://shop.semikron.com/Service-and-Support/Knowledge-Base/SEMISEL/ Choose „Step by Step design“, select “I accept the license term” and “Go anonymus”. Example Topology: AC/DC B6U In “Input parameters” change the necessary fields to adapt the values to your application requirements. For this example, just change the field “output current” to 80A. In the next step, select a package (e.g. SEMIPACK) and device (e.g. SKKD81). For the cooling, select “predefined type”; for this example, if you simulate (button “Calculate”) the heatsink P3/180 with natural air cooling, you will see that this option is valid. Usually it is possible to take a shorter version of a heatsink and add a fan to have a similar Rth(h-a) value with fewer space. 4
