The invention discloses a mounting frame for installing IGBTs in series and a method for installing IGBTs in series, wherein the mounting frame for installing IGBTs in series is a hollow regular polygon, and each side is provided with two oblong circles along the vertical direction The hole is used as the IGBT installation groove; the IGBT is fixed on the heat sink, and the heat sink is connected to the fixed splint through the oblong hole, and thus installed on the mounting frame; the IGBTs are connected in series by connecting wires; the installation height of the IGBT on each side extends clockwise Or gradually decrease counterclockwise, showing a spiral distribution. The mounting frame provided by the present invention can flexibly adjust the installation height of the IGBT to the ground. Through the flexible configuration of the installation height of the IGBT to the ground, the flexible configuration of the stray capacitance of the series IGBT to the ground is realized, and the voltage equalization characteristics of the series IGBT are optimized. And realize the compact installation of the equipment.
Description
technical field [0001] The invention belongs to the technical field of power electronic switches, and more specifically relates to a mounting frame for installing IGBTs in series and a method for installing IGBTs in series. Background technique [0002] Insulated Gate Bipolar Transistor (IGBT) is a fully-controlled switching device. Compared with thyristors, it has controllable turn-off characteristics. It is currently widely used in the field of power electronics technology, and DC Voltage regulation, high-frequency rectification, H-bridge inverter and other application methods, and a large number of power supply equipment based on IGBT technology have been derived from this. [0003] Due to the current manufacturing process problems, the IGBT has a large limit on the rated parameters, and the rated voltage parameters are about 2kV to 3kV. Therefore, when using the IGBT in a system with a voltage level of 10kV or even above 100kV, it is necessary to use a large number of IG...
