POWER SEMICONDUCTOR MODULE

摘要

Disclosed herein is a power semiconductor module including a module housing comprising an accommodation space formed therein and fixing portions formed on an external surface thereof, a printed circuit board included in the module housing, exposed through the accommodation space, and comprising circuit patterns (Cu patterns) on which power devices are arranged, and a terminal fixedly coupled to the fixing portion, and comprising an input end for receiving power and leads adhered to a circuit pattern between the power devices and for distribution of supplied current. Accordingly, stray inductance may be effectively reduced, and thus, current distribution between power devices may be balanced, thereby effectively preventing a surge voltage from increasing.
