Definitions
- the terminals (positive electrode terminal or negative electrode terminal) of a plurality of power modules are arranged in the stacking direction of the power modules. If the terminals of the power module and the capacitor are close to each other, it will be difficult to join the bus bar and the terminals. Therefore, in the power converter of Document 1, the terminals of the power module are provided on the side surface facing the second direction, the power module and the capacitor are arranged in the third direction, and the terminals are separated from the capacitor.
- the present specification provides a technique for achieving both the close contact between the terminals of a plurality of power modules and a capacitor and the easy connection between the terminals and the bus bar.
- a capacitor 6 is connected to the input end 18.
- the capacitor 6 is provided to suppress the ripple of the input current (input voltage).
- the input positive electrode end 18a of the power converter 2 is connected to the positive electrode 6a of the capacitor 6 by the power supply positive bus bar 61, and the input negative electrode end 18b is connected to the negative electrode 6b of the capacitor 6 by the power supply negative bus bar 62. ..
- a bus bar is a conductive member having a small internal resistance, and is typically made of a metal rod.
- the inverter circuit 13a has a configuration in which three sets of series circuits of two switching elements are connected in parallel.
- Switching elements 9a and 9b, switching elements 9c and 9d, and switching elements 9e and 9f form a series circuit, respectively.
- Diodes are connected in anti-parallel to each switching element.
- each of the broken lines 8a-8f corresponds to the power module.
- the power converter 2 includes 6 sets of a series circuit of two switching elements. As hardware, two switching elements constituting a series circuit and a diode connected in antiparallel to each switching element are housed in one package (power module package). In the following, when any one of the power modules 8a to 8f is shown without distinction, it is referred to as a power module 8.
- the plurality of power modules 8 and the plurality of coolers 21 are alternately laminated one by one.
- the power module 8 has a flat shape, and its wide surface is in contact with the cooler 21.
- a capacitor 6 is arranged next to the plurality of power modules 8 in the Y direction orthogonal to the stacking direction (X direction in the figure) of the plurality of power modules 8.
- the capacitors 6 are arranged so as to face the side surfaces 81 of the plurality of power modules 8.
- Three terminals 17 (positive electrode terminal 17a, negative electrode terminal 17b, midpoint terminal 17c) extend from the side surface 81 of the power module 8 facing the capacitor 6.
- the three terminals 17 are arranged along the Z direction of the coordinate system in the figure. Further, each of the three terminals 17 is made of a wide plate, and the wide surface at the tip is parallel to the side surface 81.
- the positive electrode terminal 17a is connected to the positive electrode 6a of the capacitor 6 via the extension plate 19 and the positive electrode bus bar 30, and the negative electrode terminal 17b is connected to the negative electrode 6b of the capacitor 6 via the negative electrode bus bar 40. ing.
- a power supply positive bus bar 61 and a power supply negative bus bar 62 are attached to the bus bar module 60.
- the tip of the positive electrode bus bar 30 is joined to the power supply positive bus bar 61
- the tip of the negative electrode bus bar 40 is joined to the power supply negative bus bar 62.
- the power supply positive bus bar 61 and the power supply negative bus bar 62 are bus bars that connect the input terminal 18 (see FIG. 1) of the power converter 2 and the capacitor 6.
- the capacitor 6 is bonded to the positive electrode bus bar 30 and the negative electrode bus bar 40, and is supported by the positive electrode bus bar 30 and the negative electrode bus bar 40.
- One end (upper end) of the positive electrode bus bar 30 and the negative electrode bus bar 40 is supported by the housing 50 via the bus bar module 60.
- the other ends (lower ends) of the positive electrode bus bar 30 and the negative electrode bus bar 40 are supported by the housing 50 via a plurality of power modules 8 of the stacking unit 20.
- the capacitor 6 itself does not directly touch the housing 50, but is indirectly supported by the housing 50 via the bus bars 30, 40, and the like. Although the capacitor 6 is not in direct contact with the housing 50, it has good vibration resistance because both sides are supported by the positive electrode bus bar 30 and the negative electrode bus bar 40.
- the bus module 60 corresponds to an example of a support plate.
- the X, Y, and Z directions of the coordinate system in the figure correspond to the first direction, the second direction, and the third direction, respectively.
