Abstract

The invention provides an insulated supporting device and an IGBT power module. The insulated supporting device comprises a supporting plate and insulated supporting columns. The supporting plate is of a U shape. The insulated supporting columns are arranged on the external surface of the protrusion portion of the supporting plate. According to the insulated supporting device and the IGBT power module, electrical isolation of a composite busbar of the IGBT power module is achieved through the U-shaped supporting plate and the insulated supporting columns arranged on the supporting plate, the electrical safety of the IGBT power module is improved, the composite busbar can be supported, and the composite busbar can be protected against deformation caused by stress.

Description

technical field [0001] The invention relates to converter technology, in particular to an insulating support device and an IGBT power module. Background technique [0002] With the development of AC drive technology for electric locomotives, converters using high-frequency and high-power Insulated Gate Bipolar Transistor (IGBT) power modules as switching elements are increasingly used. [0003] The composite busbar of the IGBT power module has a large input and output voltage and current at the external high-voltage interface, and the electrical safety is poor. Moreover, the composite busbar of the IGBT power module weighs 20 kg. When the IGBT power module is applied to the electric locomotive, it often produces Vibration and shock, easily damaged. In the prior art, there is no insulating support device for the composite busbar, so the electrical safety requirements cannot be met, and the composite busbar is easily deformed.
