  • Publication number: 20250079387
    Abstract: A power module includes: a first metal brazed substrate; a chipset disposed on the first metal brazed substrate, where the chipset includes at least two chips; and a clip, where the clip covers a side, away from the first metal brazed substrate, of the chipset. Each connecting unit is electrically connected to a corresponding chip. Every two adjacent connecting units are connected along a first direction through a body. Each connecting arm is arranged with respect to two adjacent chips in the chipset. The connecting arm is connected to the first metal brazed substrate. A shortest distance between the connecting arm and one of the two adjacent chips is a first shortest distance, a shortest distance between the connecting arm and the other of the two adjacent chips is a second shortest distance. A difference between the first shortest distance and the second shortest distance falls within a preset threshold.
