Novel power module structure

The invention relates to the technical field of motor controllers and particularly discloses a novel power module structure. The structure comprises a water cooling plate assembly, a driving plate fixing bolt, a capacitor assembly, a capacitor assembly fixing bolt, a driving plate, a pressing plate fixing bolt, a pressing plate, a separation IGBT and a ceramic chip, wherein the water cooling plateassembly is connected with the driving plate through a driving plate fixing bolt, the capacitor assembly is connected with the water cooling plate assembly through a capacitor assembly fixing bolt, and the pressing plate is respectively connected with the separation IGBT and the ceramic chip through pressing plate fixing bolts. The structure is advantaged in that the power of the module is changed by changing the number of the separated IGBTs, popularization of different power modules can be completed in the same arrangement mode, and cost can be greatly reduced compared with a packaging module on the market at prese
