Embodiment Construction

[0046] The present invention will be further described below in conjunction with specific embodiments with reference to the accompanying drawings.

[0047] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0048] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0049] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and sho...

Abstract

The invention provides a converter test platform and test method, and the platform comprises: an operation terminal which is configured to provide a test instruction for a control unit; a control unit which is configured to provide a test signal for the tested main loop according to the test instruction; and a tested main loop which is configured to form a test circuit of the tested power module by a bus BUS, a voltage sensor, a current sensor, an alternating current reactor and the tested power module, and generates test data according to the performance of the tested power module, wherein the control unit and the tested main loop are located in the converter.

Description

technical field [0001] The invention relates to the technical field of converters, in particular to a converter test platform and a test method. Background technique [0002] At present, the competition in the wind power market is very fierce. Major companies have increased investment in the research and development of converters, and product updates are frequent. In order to maintain the market share of wind power, various companies have also increased their investment in the research and development of converters. During the research and development process of the converter, it is necessary to test the product to verify whether the product matches the design scheme. There are many test items for products, including product system test, EMC test, environmental test test, white box test and IGBT power module test. Among them, the IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor) power module is the core component of the converter and the main devi...
