Abstract:
A power module comprising:a substrate; first and second power wirings provided over said substrate; first to Nth (N&gE;2) terminal pairs provided over said substrate, each pair thereof having first and second output terminals; and first to Nth circuits provided over said substrate, each circuit thereof being connected to said first and second power wirings, said nth circuit including, for all n (n=1 to N): a first series circuit having a first switching element connected to said first power wiring and a first diode element connected to said second power wiring which are connected in antiseries, a connecting portion thereof being connected to said first output terminal of said nth terminal pair; and a second series circuit having a second diode element connected to said first power wiring and a second switching element connected to said second power wiring which are connected in antiseries, a connecting portion thereof being connected to said second output terminal of said nth terminal pair, wherein said first to Nth circuits are arranged in the following order, all of switching elements connected to said first power wiring and all of diode elements connected to said first power wiring are arranged to form a first line extending without crossing said first power wiring, all of switching elements connected to said second power wiring and all of diode elements connected to said second power wiring are arranged to form a second line extending without crossing said second power wiring, said switching elements and said diode elements are arranged alternately in directions along said first line, along said second line, and along lines crossing said first and second lines, at least a portion of said first output terminal and at least a portion of said second output terminal are arranged between said first line and said second line for each of said first to Nth terminal pairs, and for said all n, said first switching element and said first diode element which belong to said nth circuit are connected through a first bonding wire, a middle portion of said first bonding wire being connected to said at least a portion of said first output terminal belonging to said nth terminal pair, and said second switching element and said second diode element which belong to said nth circuit are connected through a second bonding wire, a middle portion of said second bonding wire being connected to said at least a portion of said second output terminal belonging to said nth terminal pair.
