- the insulating sheet 803 for example, a laminate of PET materials or the like is used. These insulating materials are generally easy to process into a thin sheet. Further, since the insulating sheet 803 has a laminated structure, the through hole generated in each sheet is unlikely to be connected, and the insulation reliability is high.
- the distance 12 between the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b is equal to the thickness 12a of the insulating sheet 803.
- the sum of the necessary clearance 12b in consideration of the geometrical tolerance of the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b must be ensured at the minimum in production.

Therefore, the inductance from the DC power source to the power semiconductor module can be kept low, and electrical insulation can be ensured with high reliability.
- first insulating member 802a and the second insulating member constituting the bus bar assembly 800 are formed of an insulating resin member.
- the bus bar assembly 800 is formed, for example, by insert molding or the like in a state where the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b are exposed.
- the structural member 804a provided for securing the distance between the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b may be integrally formed of a resin material of the same material as the first insulating member 802a. In the example, it is formed of a metal member.

- the contact surface 13 is formed of resin materials, there is a possibility that the resin material may be contracted on the contact surface 13, and it is difficult to maintain a reliable distance between the positive and negative conductor plates. According to the bus bar assembly 800 of the present embodiment, the inductance can be reduced with high reliability.

As shown in FIG. 4, the drive circuit unit 20 a is disposed above the power semiconductor element 300. Since the drive circuit unit 20a uses a larger voltage than the control circuit unit 20b, the drive circuit unit 20a needs to have a sufficient insulation distance from other components compared to the control circuit unit 20b. Since the insulating member 802 is formed of an insulating resin material, it is not necessary to provide another insulating member between the driving circuit portion 20a and high-density mounting is possible.
- the conductor plate is generally made of copper with good electrical conductivity, and the thickness and width are determined by the current density.
- the distance between the conductor plates is preferably as close as possible for the purpose of reducing inductance.
- the distance between the conductor plate 801 and the metal boss 804a needs to be separated to a distance that allows insulation.
- the insulating sheet 803 is not the same size as the conductor plate 801, and needs to protrude to a certain distance from the edge of the conductor plate 801. .
- the insulating member 802 covering the DC side conductor plate 801 is fixed to the case 202 by, for example, bolt fastening. Accordingly, the weight of the DC side conductor plate 801 is applied to the case 220 via the insulating member 802. Thereby, concentration of stress applied to the contact portion between the lead terminal 703 and the DC side conductor plate 801 of the capacitor module 500 can be prevented. Therefore, for example, it is possible to incorporate a welded structure or the like into the joint, and it is possible to reduce the size and the number of parts.
- the current sensor 803 and the AC side conductor plate 805 are assembled to the insulating sheet 803 mounted on the bus bar assembly 800, and then the assembled bus bar assembly 800 is assembled.
- the power module 300 has a DC side terminal 301 and an AC side terminal 302, and the DC side terminal 301 and the AC side terminal are assembled by assembling the DC side conductor plate and the bus bar assembly 800 in which the AC side conductor plate is integrally assembled. Since the connection to 302 can be performed in the same assembly process, the assemblability can be improved.
- the power conversion device 200 is separated from the DC side conductor plate without integrating it with the capacitor module 500.
- the guaranteed temperature of the smoothing film capacitor cell 700 is lower than other components mounted on the power converter 200.
- the life of the film capacitor cell 700 is drastically reduced and the function as a smoothing capacitor is not satisfied. Therefore, by separating the DC side conductor plate from the capacitor module 500, it is possible to suppress the influence of tilting heat from the DC side conductor plate disposed on the upper part.
- Capacitor 500 has a case 720 for storing a capacitor cell, and case 720 is formed with positioning pins 730 that protrude in the direction in which bus bar assembly 800 is disposed, A positioning through hole 805 is formed in the insulating member 802 mounted on the bus bar assembly 800, and the positioning pin 730 is inserted into the positioning through hole 805.
- the capacitor connecting portion 703 formed on the DC side conductor plate 801 and the lead terminal 701 coming out of the capacitor can be arranged at the same position. Therefore, it is possible to improve the bonding reliability.
- the configuration of the power conversion device according to the second embodiment will be described.
- the part that is changed from the first embodiment is only the structure of the bus bar assembly 800, and therefore the description of the other configuration is omitted.
- FIG. 5B is a schematic diagram illustrating a cross section of the bus bar assembly 800 according to the second embodiment.
- a first structural member 804a protruding from the first insulating member 802a and a second structural member 804b protruding from the second insulating member 802b are formed.

- the first structural member 804a is formed so as to protrude from the exposed surface 14 in the normal direction of the exposed surface 14 of the positive-side conductor plate 801a.
- the second structural member 804b is formed so as to protrude from the exposed surface 15 in the normal direction of the exposed surface 15 of the negative-side conductor plate 801b.
- the first structural member 804a and the second structural member 804b are formed such that the sum of the protruding distance of the first structural member 804a and the protruding distance of the second structural member 804b is the conductor plate distance 12 shown in the first embodiment.
- the first insulating member 802a has a convex first structural member 804a and the second insulating member 802b has a convex second structural member 804b. Even if the relative position of the second structural member 804b is shifted due to vibration or the like, the second structural member 804b does not contact the first insulating member 802a or the second insulating member 802b. Therefore, the first insulating member 802a and the second insulating member 802b formed of a resin material can be prevented from being closed, and the distance between the conductor plates can be maintained with high reliability.
- through holes are provided in the first structural member 804a and the second structural member 804b. Since the through holes exist on the same axis, when the bus bar assembly 800 is mainly fixed with screws, the screws 800a and 800b can be fixed with screws through the respective through holes 804. Therefore, two different parts can be fixed at the same time, and the number of assembling steps can be reduced.
- FIG. 5C is a schematic diagram illustrating a cross section of the bus bar assembly 800 according to the third embodiment.
- the difference from the second embodiment is that a positioning hole 16 is formed in the insulating sheet 803, and the first structural member 804a or the second structural member 804b is formed so as to penetrate the positioning hole 16.
- the position is not defined in the exposed surface in-plane direction of the positive electrode side conductor plate 801a or the negative electrode side conductor plate 801b. If there is a region where the insulating sheet 803 is not formed between the exposed surface of the positive-side conductor plate 801a and the exposed surface of the negative-side conductor plate 801b, a necessary distance for ensuring insulation can be secured in that region. Therefore, there is a risk of impairing reliability.
- the bus bar assembly 800 of the present embodiment since the positioning hole 16 is formed in the insulating sheet 803, the position in the in-plane direction of the insulating sheet 803 is determined, so that the assembly workability is improved, the displacement with respect to vibration, etc. It becomes possible to suppress. Accordingly, it is possible to further improve the insulation between the positive and negative electrodes.
- 5 (d) and 5 (e) are diagrams showing another embodiment for securing a distance between the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b.
- the structural member for securing the distance between the pole-side conductor plate 801a and the negative-electrode side conductor plate 801b is a separate member from the first insulating member 802a and the second insulating member 802b.
- the bus bar assembly 800 shown in FIG. 5D has recesses formed in the first insulating member 802a and the second insulating member 802b made of insulating resin.
- the recesses are formed to face each other.
- a structural member 806 is inserted into the recess.
- the bus bar assembly 800 shown in FIG. 5 (e) has a T-shaped structural member 807.
- the T-shaped structural member 807 is an outer peripheral portion of the first insulating member 802a and the second insulating member 802b, and is disposed between the first insulating member 802a and the second insulating member 802b.
- the distance between the positive electrode side conductor plate 801a and the negative electrode side conductor plate 801b may be secured also by using a structure as shown in FIG. 5 (d) or FIG. 5 (e).
