Beschreibung
Zusammenfassung:	The utility model relates to a three-level module with high power, mainly comprising a water-cooling plate (1), a high power switching device (4), a connecting copper bar, a buffer circuit plate (12), a wind-cooling radiator (13). The utility model is characterized in that the high power switching device (4) is arranged on the water-cooling plate (1). The connecting copper bar is arranged between the water-cooling plate (1) and the buffer circuit plate (11). The buffer circuit plate (11) is fixed on the wind-cooling radiator (13). Different radiating methods are applied according to the different radiators, which solve the radiation problem of the high power device. The utility model adopts hierarchical design, simplifies the manufacturing technique and enhances the reliability of the power module by step installation and check and test.
