Furthermore, if there are some modules, their positions and adjacencies can be adjusted as needed.

[0036] If it is intended to describe a situation where a component or module is directly before another component or module, this document will use the expression “directly before” or “before and adjacent to”.

In order to clearly show the internal structure of the controller, the upper cover is omitted in the schematic diagram. The bottom shell 100 of the controller is provided with a power module 200, a capacitor 300, a terminal block 400, a phase conductive structure 500 and a power conductive structure 600, wherein the power module 200 is, for example, located in the middle area of ​​the bottom shell 100. The power module 200 is, for example, an intelligent power module (IPM) including a plurality of insulated gate bipolar transistors (IGBT). Of course, the power module 200 in the controller is not limited to Figure 1The controller of the present application is also applicable to various other power modules 200. The upper side of the power module 200 is provided with three groups of bus voltage input terminals, including a first bus voltage input positive terminal 204, a first bus voltage input negative terminal 205, a second bus voltage input positive terminal 206, a second bus voltage input negative terminal 207, a third bus voltage input positive terminal 208 and a third bus voltage input negative terminal 209; the lower side of the power module 200 is provided with three phase output terminals, including a U-phase output terminal 201, a V-phase output terminal 202 and a W-phase output terminal 203; the capacitor 300 is, for example, a thin film capacitor, and the capacitor 300 is, for example, located at the upper part of the bottom shell 100, located at the upper side of the power module 200, and the capacitor 300 is located in the upper area of ​​the bottom shell 100. The three groups of bus voltage input terminals on the upper side of the power module 200 are connected to the capacitor 300.

For example, the phase conductive structure 500 includes a first conductive structure 510, a second conductive structure 520, and a third conductive structure 530, which correspond to the three phase output terminals on the lower side of the power module 200. For example, the phase conductive structure 500 has a leftward bend. One end of each phase conductive structure 500 is connected to a phase output terminal on the lower side of the power module 200, and the other end is connected to the terminal block 400.

One end of the fourth conductive structure 610 is connected to the input terminal of the capacitor 300, and the other end is connected to the power output terminal of the terminal block 400. Specifically, one end of the fourth conductive structure 610 is connected to the first end of the capacitor 300, and the other end of the fourth conductive structure 610 is connected to the positive power output terminal of the terminal block 400.

The fourth conductive structure 610 is bent to the left near the side near the terminal block 400, and the fifth conductive structure 620 is longitudinally bent near the terminal block 400. Therefore, near the terminal block 400, the fourth conductive structure 610 and the fifth conductive structure 620 are offset and arranged side by side on a horizontal plane parallel to the terminal block 400.

[0041] Furthermore, a support member 700 is provided at the phase output end on the lower side of the power module 200. The support member 700 is, for example, an insulating member.

Furthermore, the other end is also provided with a power lead positive terminal fixing hole 603, parallel to the power lead positive terminal connection hole 602, for connecting the fourth conductive structure 610 to the power lead positive terminal of the terminal block 400. The fourth conductive structure 610 is also provided with a fixing hole 604 for fixing the fourth conductive structure 610 to the support member 700. Similarly, the fifth conductive structure 620 is similar to the fourth conductive structure 610 and will not be described in detail.

[0043] The terminal block 400 is, for example, in a strip shape and is made of an insulating material.

It can effectively isolate the working magnetic field of the power module 200 and prevent the connecting screws from falling into the bottom of the bottom shell 100.

[0044] The terminal block 400 also includes a groove 403, which corresponds to, for example, the end of the conductive structure extending into the insertion hole 401. The groove 403 is, for example, a retaining groove. The end of the conductive structure connected to the terminal block 400 is embedded in the groove 403 and fixed to the terminal block 400 by screws 404. When making external connections, screws 405 are used to connect and secure the external wiring to the corresponding conductive structure at the corresponding position on the terminal block 400.

Specifically, at least two of the first conductive structure, the second conductive structure, and the third conductive structure are provided with current sensors to detect line current.

[0047] Figure 4 The exploded diagram of the controller of the first embodiment of the present invention is shown, and the Figure 2 The connection structure shown is Figure 4 It can be seen that the bottom shell 100 is provided with a first limiting structure 101 and a second limiting structure 102 for positioning at the edge of the position corresponding to the support member 700, wherein the first limiting structure 101 is, for example, L-shaped, which corresponds to the upper left corner edge of the support member 700, and the second limiting structure 102 is, for example, strip-shaped, which corresponds to the right edge of the support member 700. The support member 700 can be conveniently positioned and fixed by the first limiting structure 101 and the second limiting structure 102 so that it corresponds to the power module 200, reducing the difficulty of assembly.

Taking the first conductive structure 510 as an example, a current sensor (not shown) is first inserted through the upper end of the first conductive structure 510. The current sensor's positioning hole is aligned with the sensor fixing hole on the first conductive structure 510, and the two are secured together using screws. A support member 700 is then provided on the bottom housing. The lower end of the first conductive structure 510 is then inserted into the corresponding insertion hole in the terminal block 400 and embedded in the groove 403 of the terminal block 400. The lower end of the first conductive structure 510 is then secured to the terminal block 400 using screws.
