IGBT module testing device

Abstract

The invention relates to the technical field of testing devices, and discloses an IGBT module testing device. The IGBT module testing device comprises a supporting plate, wherein the middle part of the upper surface of the supporting plate is fixedly connected with a regulation and control device; the left end of the upper surface of the supporting plate is fixedly connected with a test display; the right end of the upper surface of the supporting plate is fixedly connected with a baffle plate; an accommodating groove is formed in the right end of the supporting plate; sliding rails are fixedly connected to the inner front side wall and the inner rear side wall of the accommodating groove; and the inner ends of the sliding rails are slidably connected with sliding blocks. The IGBT module testing device can fix an IGBT module to be tested by means of the cooperation of a moving plate, an elastic spring, the sliding rails, the sliding blocks, the baffle plate and an extrusion plate, andcan automatically regulate and control a test element connecting end by means of the cooperation of a servo motor, a rotating shaft, a first gear, a second gear, a main shaft, a limiting pipe, a threaded rod, a moving pipe, a connecting plate, a connecting block, a limiting spring, a first bent plate and a second bent plate.

Description

technical field [0001] The invention relates to the technical field of testing devices, in particular to an IGBT module testing device. Background technique [0002] At present, the IGBT driver is a device that drives the IGBT and regulates its overall performance. It not only affects the dynamic performance of the IGBT, but also affects the cost and reliability of the system. The selection of the driver and the calculation of the output power determine the performance of the commutation system. Reliability, insufficient driver power or wrong selection may directly lead to damage to the IGBT and the driver. The IGBT module is an important component in power electronic equipment. It is necessary to test the IGBT module before it is put into use, after maintenance or when the product is accepted. The current IGBT module test device needs the staff to hold the test components to test the IGBT module when using it, which makes the staff more prone to danger during the test, and ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a kind of IGBT module testing device, which has the advantages of being able to automatically test the IGBT module and fixing the IGBT module at the same time, which solves the problem that the IGBT module testing device needs staff when it is in use. Hand-held test components are used to test the IGBT module, which causes the staff to be more prone to danger during the test, and the safety of use is relatively low. At the same time, it is more inconvenient to fix the IGBT module, and the practicability is low, which is not conducive to popularization and use.
