Example Embodiment
[0027] Example 1: Such as Figure 1 to 3 As shown, the power module module involved in the present invention includes an IGBT power module and a capacitor module. The IGBT power module is composed of three IGBT power module structures side by side. The capacitor module includes a capacitor group 9, a positive busbar copper bar 8, and a middle Insulation layer 7 and negative busbar copper bar 6.
[0028] The IGBT power module structure includes an IGBT module group, an IGBT drive board 2, a heat sink 3 of the IGBT module, a DC bus bar 4 connected to the IGBT module, and an AC copper bar 5 used for paralleling the IGBT module. The IGBT module group is composed of two IGBT modules 1 in parallel, installed on the liquid-cooled radiator 3. The IGBT module 1 can be a commonly used 1000A power module (for example, the fourth generation FF1000R17IE4 of Infineon, Germany, or the same in the subsequent The package size of the fifth generation FF1800R17IP5), can also be silicon carbide sem...
