ANPC power module

An ANPC power module disclosed by the present invention comprises at least one power module, the power module comprises six switch assemblies, a DC end, a GND end and an SW end, the six switch assemblies comprise two outer tubes, two inner tubes and two clamping tubes, and an additional capacitor leading-out terminal is arranged at the electrical connection position of each inner tube and a switch bridge arm. The capacitor leading-out terminals are used for arranging a high-frequency filter capacitor, and the two ends of the high-frequency filter capacitor are electrically connected with the capacitor leading-out terminals corresponding to the two switch bridge arms respectively. The invention can effectively improve the dynamic voltage spike at the moment of high-frequency switch action, improve the oscillation frequency, increase the allowable working voltage range of the device, and prevent EMI noise from jumping out of the system. 本发明公开了一种ANPC功率模块，包括至少一个功率模块，所述功率模块包括六个开关组件、DC端、GND端和SW端，所述六个开关组件包括两个外管、两个内管
