Embodiment

For making those of ordinary skill in the art be expressly understood purpose, technical scheme and the advantage of the utility model more, the utility model is done further elaboration below in conjunction with accompanying drawing and embodiment.

As depicted in figs. 1 and 2; Inverter power module disclosed in the utility model includes a housing 10; This housing 10 is formed with an accommodation space 100, arranges IGBT (Insulated Gate Bipolar Transistor) module 20, absorption electric capacity 30, filter capacitor 40, input terminal group 50, lead-out terminal group 60 and controls plate module 70 to be used to take in.

IGBT module 20 is arranged at the centre of the accommodation space 100 of this housing 10; And will absorb the place, top that electric capacity 30 is located at this IGBT module 20; The IGBT module 20 that two one group absorption electric capacity 30 correspondences are two one group, so arrangement makes that absorption electric capacity 30 is nearest apart from IGBT module 20; Improve the assimilation effect that absorbs electric capacity 30, guaranteed the performance of power model.

Filter capacitor 40 can adopt thin-film capacitor; It is arranged at the place, top that absorbs electric capacity 30; Input terminal group 50 is located at the front portion of accommodation space 100 and is located, lead-out terminal group 60 then is located at the right part place of accommodation space 100, like this; Input terminal group 50 makes that more near filter capacitor 40 filter effect of filter capacitor 40 is more remarkable.

Consult accompanying drawing; Place, both sides in filter capacitor (thin-film capacitor) 40 respectively is provided with a mounting panel 400; Be formed with at least one first perforation 401 on this mounting panel 400; And the place, both sides that in this accommodation space 100, is positioned at filter capacitor 40 respectively is provided with a bracing frame 101, is formed with at least one second perforation 102 on this bracing frame 101, and two mounting panels 400 of this filter capacitor 40 are placed in corresponding bracing frame 101 respectively; Use screw to pass first perforation 401 and also screw togather nut on it, thereby realize the fixed installation of filter capacitor 40 with corresponding second perforation 102.
