Problems solved by technology

Usually, the test of the protection function of the driver board needs to be carried out with the IGBT module after installation, but once the protection fails, it will directly lead to the burning of the IGBT module, and may also cause personal injury to the debugger

Embodiment

[0018] Such as figure 1 As shown, a driving protection simulation test device of the present invention includes an IGBT module, a driving board 1, a control board 2, a power board 3, a first analog test circuit 4, a second analog test circuit 5, and a third analog test circuit 6. .

[0019] The IGBT module is a composite fully-controlled voltage-driven power semiconductor device composed of BJT bipolar transistors and MOS field effect transistors.

[0020] The driving board 1 is a conventional PCB circuit board, and the driving board mainly provides power for turning on and off the IGBT module. The drive board is double-sided design, and the surface is sprayed with three anti-paints. The drive board is provided with C1M, C2M, C3M, C4 and C5 connectors. C1M, C2M and C3M connectors are used to connect to the IGBT module. The 1 of the C1M connector Pin is the collector C of the U-phase upper-arm IGBT module, pin 4 is the emitter E of the U-phase upper-arm IGBT module; pin 5 of the C...

Abstract

The invention relates to a drive protection simulation test device, which comprises an IGBT module, a drive board, a control board, a power supply board, a first simulation test circuit, a second simulation test circuit and a third simulation test circuit. By setting the analog test logic in the control board software, the test is carried out under the low-voltage control power supply, and the drive protection function test is completed before the drive board is installed on the machine, which can effectively prevent the burning of the IGBT module due to protection failure, and is safer and more reliable. . The on-off of the line is completed by flipping the switch, without frequent plugging and unplugging of the connector. The connection of the external battery is confirmed before the start of the test to prevent the poor contact caused by the pressure of the cable when the cable is connected to the connector, which will affect the test result.

Description

Technical field [0001] The invention relates to the detection field of a circuit board of a rail passenger car power supply device, in particular to a driving protection simulation test device. Background technique [0002] The drive circuit is located between the main circuit and the control circuit to amplify the signal of the control circuit. The core part of the drive circuit of the rail passenger car power supply device consists of six single-tube IGBT modules (constitute a three-phase bridge inverter) and a drive board. The drive board mainly provides power for the opening of the IGBT module and has certain protection functions. The specific work When receiving the drive control information from the control board to turn on the IGBT module, complete the turn-off of the IGBT module for protection in the event of a fault, and feedback relevant information to the control board. Usually the test of the protection function of the drive board needs to be carried out with the IGB...
