Abstract

The device discloses a power module applied to a rail vehicle. The power module comprises a heat radiator layer, a main circuit layer, a control layer and an electrical layer, wherein the main circuitlayer comprises a substrate and a three-bridge-arm power semiconductor circuit, the first surface of the substrate is fixedly connected with the first surface of the heat radiator layer, the three-bridge-arm power semiconductor circuit is arranged on the second surface of the substrate; the control layer is electrically connected with the three-bridge-arm power semiconductor circuit, and is usedfor controlling an operating state of the three-bridge-arm power semiconductor circuit; the electrical layer is arranged between the main circuit layer and the control layer, the electrical layer comprises power terminals and a lamination busbar, and the power terminals are used for realizing electrical transmission between the substrate and the lamination busbar. Compared with the existing powersemiconductors, the power module provided by the invention integrates the control circuit inside equipment, so that an additional control circuit is not needed during operation, thus the power modulecan realize intelligent control functions such as driving , monitoring, protection and diagnosis, and improves the universality degree of the equipment.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular, to a power module 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 present invention provides a power module for rail vehicles, which includes: [0004] a radiator layer ...
