摘要： PROBLEM TO BE SOLVED: To more appropriately suppress generation of common mode noise due to the switching of a switching element.SOLUTION: When a metal housing 24 for housing four layers substrate including a P layer 34 and an N layer 36 is grounded, inductances of the P layer 34 and the N layer 36 are denoted as "Lp" and "Ln", respectively, and stray capacitances between the P layer 34 and the housing 24 and between the N layer 36 and the housing 24 are denoted as "Cp" and "Cn", respectively, the arrangement of the four layers substrate in the housing 24 is performed with an adjustment of each of distances between the P layer 34 and the housing 24 and between the N layer 36 and the housing 24 so that a relational expression: Ln*Cn-LP*Cp=0 is satisfied, and formation of the P layer 34 and the N layer 36 of the four layers substrate is performed with an adjustment of each surface area of the P layer 34 and the N layer 36. Accordingly, in the equivalent circuit of the structure of a switching element device 20, common mode current caused by switching a switching element can be ideally reduced to a value of zero.

摘要： PROBLEM TO BE SOLVED: To suppress generation of common mode noise due to switching of a switching element more properly.SOLUTION: Two coolers 31, 32 are formed of a conductor and placed on the opposite sides while holding a card-like element 22 including a switching element and a P bus bar 26p and an N bus bar 26n, extending therefrom while facing each other, therebetween, and are connected by a planar connection 36 formed of a conductor and placed between both bus bars 26p, 26n, and then grounded. Both bus bars 26p, 26n and the connection 36 are formed and arranged so as to satisfy a relational expression Ln×Cn-Lp×Cp=0, where the Lp and Ln are inductances from the elements 22 in both bus bars 26p, 26n to a predetermined position facing the connection 36, and the Cp and Cn are capacitances between both bus bars 26p, 26n and the connection 36.
