Title:
POWER MODULE, POWER MODULE WITH DRIVE CIRCUIT, INDUSTRIAL EQUIPMENT, ELECTRIC AUTOMOBILE AND HYBRID CAR
Document Type and Number:
WIPO Patent Application WO/2018/043535
Kind Code:
A1
Abstract:
This power module (PM) (10A) is provided with: a first insulating substrate (21D) that is provided with a first conductive layer (24D) on the surface; a first semiconductor device Q1 that is arranged on the first conductive layer (24D) and has a first electrode connected to the first conductive layer (24D); a first signal electrode (1) that is formed on the surface of the first insulating substrate (21D) and is connected to a second electrode of the first semiconductor device Q1; a second signal electrode (2) that is formed on the surface side of the first insulating substrate (21D) and is connected to a third electrode of the first semiconductor device Q1; and an insulating layer (3) that is arranged on the first insulating substrate (21D). The first signal electrode (1) and the second signal electrode (2) are arranged such that the insulating layer (3) is interposed therebetween. A PM (101) with a drive circuit is provided with: a PM (10S) wherein a power semiconductor device is sealed; an upper cooling device (12U) that is arranged on a first sealing surface (10a) of the PM (10S); and a gate driver (180) that drives the PM (10S) and is mounted on a surface (10u) of the upper cooling device (12U), said surface (10u) being on the reverse side of the surface that is in contact with the PM (10S).
