Abstract

An integrated power module comprises a heat radiator layer, a main circuit layer and a control circuit, wherein the main circuit layer comprises a three-phase bridge arm power semiconductor circuit and at least two sets of lining plates, the first set of lining plates and the second set of lining plates are arranged on the first side surface and the second side surface of the heat radiator layer in a contact manner, and power semiconductor chips in the three-phase bridge arm power semiconductor circuit are arranged on the first set of lining plates and the second set of lining plates in groups; and the control circuit is electrically connected with the three-phase bridge arm power semiconductor circuit, and is used for controlling operating states of the three-phase bridge arm power semiconductor circuit. Compared with the existing power semiconductors, the integrated power module integrates the control circuit inside equipment, such that a control circuit does not need to be additionally configured in operation, thereby enabling the H-bridge arm double-side heat dissipation power module to realize intelligent control functions such as driving, monitoring, protecting and diagnosis,and improving the universality degree of the equipment.

Description

technical field [0001] The invention relates to the technical field of power electronics, in particular to an integrated power module. 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 an integrated power module, which includes: [0004] radiator layer; [0005] The ...
