Abstract

A DC bus bar design device including a radiator, An IGBT module is arranged on one side of the radiator, At one side of the IGBT module, a fixed cop bar is arranged, the fixed copper bar comprises a positive fixed copper bar and a negative fixed copper bar, Between that positive fix copper bar and the negative fix copper bar, an insulating layer is arranged, A linear bus bar is arranged on the other side of the fixed cop bar, The linear bus bar comprises a positive linear bus bar and a negative linear bus bar, wherein a positive connection hole is arranged on the surface of the positive linearbus bar, a negative connection hole is arranged on the surface of the negative linear bus bar, fixed holes are arranged inside the positive connection hole and the negative connection hole, and a capacitor bank is arranged at the bottom of the linear bus bar. A linear bus bar, a connection hole and a fixed hole are arrange on that surface of the linear bus bar, and positive and negative connection holes are arranged on the surface of the linear bus bar, so that the capacitor bank adopts the connection mode of positive and negative series connection on the linear bus bar, thereby increasing the connection strength and reduce the inductance.

Description

technical field [0001] The invention relates to the field of electronic equipment, in particular to a DC busbar design device. Background technique [0002] In recent years, power semiconductors have developed rapidly, new devices have been updated faster, and high-power power electronic inverters are used in various industries. With the demand of the market, high-power power electronic inverters are developing in the direction of higher switching frequency, smaller size and lower cost. The development of high-power power electronic inverters depends on the development of high-power IGBT modules. However, the greater the power of the IGBT, the greater the influence of stray capacitance and stray inductance during operation, the greater the heat generation, and the higher the damage rate; increase, the reliability of the IGBT module decreases. [0003] Therefore, it is necessary to invent a DC busbar design device to solve the above problems. Contents of the invention ...
