Abstract

The invention provides a power module, a motor controller comprising the power module, a driving assembly and a vehicle, and belongs to the technical field of vehicle driving control. The invention discloses a power module. The power module comprises a converter bridge; the converter bridge is a multi-phase circuit; wherein the converter bridge comprises at least one active switch chip and at least one passive follow current chip; in at least one bridge arm of the converter bridge, the ratio of the total area of the passive follow current chip to the total area of the active switch chip satisfies a first ratio, and the first ratio is greater than or equal to 0.6. According to the power module provided by the embodiment of the invention, the miniaturization of the power module is realized.
