Embodiment Construction

[0028] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0029] An embodiment of a general-purpose IGBT power module test system of the present invention:

[0030] For power modules, the core components of most power electronic products, on-site R&D tests or factory tests are required, but the test tools for power modules are too messy and have poor compatibility. R&D, contract, and after-sales test requirements provide a general-purpose compatible SVG, flexible direct power module, output optical communication messages to interact with power modules of power electronics products, and meet power modules in the development process of power electronics products The double-pulse test and the switch wave test in the manufacturing process can meet the communication test of the power module of different communication protocols and the trigger test of the semiconductor tube by modifying the relevant procedures...

Abstract

The invention provides an IGBT power module test system. The system comprises an optical fiber communication interface, an acquisition interface and a fault wave recording interface, wherein the optical fiber communication interface is used for connecting an SVG power module / a flexible direct-current power module, the acquisition interface is used for acquiring the output voltage of the SVG powermodule / the flexible direct-current power module, and the wave fault recording interface is connected with a fault wave recording module and is used for performing wave recording on the SVG power module / the flexible direct-current power module; the output end of the fault wave recording module is connected with a computer through a photoelectric conversion communication module; the computer is used for displaying the test results of the SVG power module / the flexible direct-current power module; the system further comprises an optical fiber driving interface used for connecting a wind power converter power module / photovoltaic inverter power module; and the optical fiber driving interface is used for transmitting driving signals to test the wind power converter power module / photovoltaic inverter power module. The test system of the invention is suitable for testing various power modules, and has the advantages of universality, portable convenience, stable work, and high safety during test.

Description

technical field [0001] The invention belongs to the technical field of IGBT power module testing, in particular to an IGBT power module testing system. Background technique [0002] In the 21st century when new energy power generation technology is in full swing, a large number of power electronic products have been put into use, including photovoltaic grid-connected inverters, wind power converters, static var generators, and flexible DC transmission converter valves. For most manufacturers of power electronic products, the core power components used in their products are insulated gate transistors (IGBTs). Whether it is the in-factory R&D test or the factory test of the power module, the test system is too messy, too bulky and has the problem of poor compatibility. [0003] The explosive development of power electronic products has also increased the difficulty of after-sales service. In most cases, faulty power modules need to be transported long distances back to the f...
