Abstract

The present invention relates to a semiconductor power device and a power processing assembly for the semiconductor power device, wherein the power processing assembly includes an insulating substrate; a plurality of chips arranged on the insulating substrate; A sensor body located under the selected chip, and an electrical connector connected to the sensor body and passing through the insulating substrate. The power processing component can reduce the risk of damage to the temperature sensor due to short-circuit arc breakdown, and at the same time solve the problem of a large error between the temperature detection result of the temperature sensor and the actual operating temperature of the selected chip, which is beneficial to the operating temperature of the chip. Precise control.

Description

technical field [0001] The present invention relates to a semiconductor electronic device, in particular to a power processing assembly for a semiconductor power device and a semiconductor power device including the power processing assembly. Background technique [0002] With the continuous development and progress of science and technology, semiconductor power devices are widely used in rail transit, smart grid, aerospace, electric vehicles and new energy equipment and other fields. like figure 1 As shown, the power processing assembly is similar to the circuit board structure with components, and is the core unit to realize the basic functions of the semiconductor power device 100'. The performance of the power processing assembly is closely related to the operating temperature of its chip 22', and its operating temperature is slightly Variations may cause a sudden drop in the performance of power processing components, so it is particularly important to precisely contro...
