The second connector 240 is electrically connected to the first connector 130. The negative electrode terminal of the supporting capacitor 500 is electrically connected to the second bus bar terminal 250 through the second conductive element 700.

In some embodiments, referring to fig. 5, the first conductive element 600 and the second conductive element 700 are both located on a side of the second printed circuit board 210 facing away from the first printed circuit board 110. In one aspect, the surface of the second printed circuit board 210 facing away from the first printed circuit board 100 has a larger space, thereby optimizing the layout of the electrical components on the second printed circuit board 210; on the other hand, when the first conductive element 600 and the second conductive element 700 are mounted on the second printed circuit board 210, the mounting process may be performed on the same side of the second printed circuit board 210, so that the process of flipping the second printed circuit board 210 is omitted, and the process of the second printed circuit board 210 may be simplified.

Therefore, the second insulating connecting piece 260 is sleeved outside the second bus terminal 250, so that the second bus terminal 250 is insulated from the second printed circuit board 210, the second bus terminal 250 has a good function of guiding the current to pass through the second printed circuit board 210, the current guiding function of the second bus terminal 250 is improved, and the safety of the second bus terminal 250 in the using process is improved.

In some embodiments, referring to fig. 1, fig. 3 and fig. 6, the second pcb 210 is located at a side of the first pcb 110 where the power transistor 120 is located.

In some embodiments, referring to fig. 2 and 3, the controller 1000 includes a heat sink 300 and a first insulating connector 400. The heat sink 300 is located at a side of the first printed circuit board 110 facing away from the second printed circuit board 210. The heat sink member 300, the first printed circuit board 110 and the second printed circuit board 210 are connected by a first insulating connector 400. Since the power tube 120 is easy to generate heat, the temperature of the first printed circuit board 110 is easy to rise due to the temperature rise of the power tube 120, and the heat on the first printed circuit board 110 is dissipated and discharged in time through the heat dissipating part 300, thereby avoiding the over-temperature of the controller 1000 in time. The heat sink 300, the first printed circuit board 110 and the second printed circuit board 210 are fixed by the first insulating connector 400, so that the structure of the controller 1000 is more stable.

Specifically, the first insulating connector 400 may be an insulating copper pillar.

The other end of the supporting capacitor 500 is connected to the first printed circuit board 110. Because the supporting capacitor 500 is located in the accommodating groove 300a, the contact area between the supporting capacitor 500 and the heat dissipation portion 300 is increased, so that the supporting capacitor 500 can dissipate heat in time, and the height of the controller 1000 can be reduced, so that the overall space of the controller 1000 is compact.

In another embodiment, referring to fig. 2 and 3, the first printed circuit board 110 is formed with a relief area 110 a.

It is understood that the avoidance region 110a refers to an avoidance space formed on the first printed circuit board 110 for avoiding the support capacitor 500. For example, referring to fig. 2 and fig. 3, the width of the first printed circuit board 110 may be smaller than the width of the second printed circuit board 210, and the first printed circuit board 110 and the second printed circuit board 210 are disposed opposite to each other, so that a avoiding region 110a is formed in the width direction of the first printed circuit board 110, and the other end of the supporting capacitor 500 is connected to the second printed circuit board 210 through the avoiding region 110 a. A notch for avoiding the supporting capacitor 500 may also be formed on the first printed circuit board 110, so that the supporting capacitor 500 can pass through the notch, and the first printed circuit board 110 is prevented from interfering the connection between the supporting capacitor 500 and the second printed circuit board 210. That is, one end of the supporting capacitor 500 is located in the receiving groove 300a, and the other end of the supporting capacitor 500 is connected to the second pcb 210 through the avoiding region 110 a. In this way, it is advantageous to further reduce the height of the controller 1000 in the direction of the first printed circuit board 110 and the second printed circuit board 210, so that the overall space of the controller 1000 is more compact.
