Description

Technical Field

[0002] With the development of the electrification era, urban rail transit subway trains have become an important means of transportation in today's cities. Therefore, the maintenance of urban rail transit is extremely important.

[0003] The auxiliary inverter module is one of the important components in the auxiliary inverter box. It is the last output process of the entire auxiliary inverter box in inverting the grid voltage from 1500V to 380V. After completing the inversion of 380V, the module can stabilize the voltage at 380V and filter. Among them, the IPM module in the auxiliary inverter module plays the role of opening and closing, and the IPM trigger board controls the opening and closing of the IPM module.

Although this installation method can improve space utilization, due to the vibration of the power module during operation, the contact point between the IPM trigger board and the power module is easy to loosen, increasing the failure rate. At the same time, with the development of miniaturization of functional modules, the upgraded power module is even smaller and cannot be directly plugged into the existing IPM trigger board.
