Embodiment Construction

[0008] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0009] The present invention is a novel fuel injection pump new energy vehicle motor controller busbar integration technology. By integrating all components of the inverter busbar circuit, including copper bars, busbar main capacitors and connecting terminals, and finally injecting molding on the outside of all components, the Enclosed in a plastic case.

[0010] The positive and negative copper bars of the bus are stacked up and down, and the middle is insulated with an insulating film, which can minimize the parasitic inductance of the bus line.

[0011] Below the positive and negative copper bars of the bus, the pins of...

Abstract

The invention relates to a new energy automobile motor controller bus integration technology. The new energy automobile motor controller bus integration technology is characterized in that all elements of an inverter bus circuit are integrated together and comprises a copper bar, a bus main capacitor and a connecting terminal, and finally the exteriors of all the elements are subjected to injection molding; and all the elements are sealed in a plastic shell, an electric structure of a direct current bus in the existing motor controller is simplified, the parasitic inductance is reduced, peak pulse generated by a high-power switching circuit is effectively restrained, and a power switching circuit is protected from being damaged. The structure is simpler and more compact, a module design concept is highlighted, and the production efficiency and the maintenance efficiency are greatly improved.

Description

technical field [0001] The invention relates to a novel bus circuit integration method, in particular to a new energy vehicle motor controller bus integration technology. Background technique [0002] The busbar circuit structures of motor controllers appearing on the market vary widely, and they are basically improved step by step according to the original products of the company, and most of them are pieced together inside the controller. The lack of modular design ideas is not conducive to product assembly and future maintenance. Moreover, due to the complex structure and the large area of ​​the loop surrounded by the busbar, the parasitic inductance of the busbar is very large, and the electrical hazard is relatively large. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a new energy vehicle motor controller bus integration technology to solve this problem. [0004] The present invention is achieved through the f...
