Title:
SEMICONDUCTOR POWER CONVERTER
Document Type and Number:
WIPO Patent Application WO/2007/080922
Kind Code:
A1
Abstract:
In a semiconductor chip structure (20), a P bus bar (23) and an N bus bar (24) are
arranged to face each other, and a first power semiconductor chip (21) is attached
on the lower plane of the P bus bar (23), and a second power semiconductor chip (22)
is attached on the upper plane of the N bus bar (24). Then, an AC bus bar (25) is arranged
between a high side semiconductor chip (21) and a low side semiconductor chip
(22) by being electrically connected with the chips. A capacitor (30) shares
upper and lower (positive and negative) electrodes with the semiconductor chip
structure (20) by the P bus bar (23) and the N bus bar (24) of the semiconductor chip
structure, and the semiconductor chip structure (20) and the capacitor (30)
use the P bus bar (23) and the N bus bar (24) as common supports. Thus, the semiconductor
chip structure (20) and the capacitor (30) are arranged adjacent to each other
in parallel, and a semiconductor power converter (10) is constituted.
