Abstract

The invention provides an H bridge arm power module for a rail transportation vehicle. The H bridge arm power module comprises a heat radiator layer which has a coolant inlet and a coolant outlet in communication with a cavity of the heat radiator layer, a main circuit layer which comprises a liner plate and an H bridge power semiconductor circuit, wherein the liner plate is contactably arranged on the heat radiator layer, a first surface of the liner plate is in contact with a first surface of the heat radiator layer, and the H bridge power semiconductor circuit is arranged on a second surface of the liner plate. The H bridge arm power module also comprises a control layer which is electrically connected to the liner plate through a pin and is used for controlling the working state of thepower semiconductor circuit. Compared with an existing power semiconductor, the power module provided by the invention has the advantages that the control circuit is integrated in equipment, the additional configuration of the control circuit is not needed during operation, thus the power modules can achieve intelligent control functions such as driving, monitoring, protection and diagnosis, andthe generalization of the equipment is improved.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an H-bridge arm power module used for rail vehicles. Background technique [0002] Power semiconductor devices are widely used in rail transit, industrial frequency conversion and other fields, but standard package power semiconductor devices only have the function of switching tubes, and the integration level is not high. As one of the core components of the converter, the converter module is composed of standard packaged power semiconductor devices, heat sinks, low-inductance busbars, gate drivers and structural parts, etc., due to the limitations of structural form, device layout and device functions , There are still many imperfections in terms of power density, intelligence and convenient application. Contents of the invention [0003] In order to solve the above problems, the invention provides a kind of H bridge arm power module for rail vehicle, it comprises:...
