Zusammenfassung:The invention relates to a current detection device, a power module and electric equipment. The current detection device comprises a current sensing element and a soft magnetic element. The current sensing element is arranged at a first end of a measuring area of a conductor in a second direction, and the conductor is suitable for being connected to a current converging end; the soft magnetic element is arranged on the periphery of the measurement area of the conductor in the first direction; wherein the first direction may be different from the second direction. According to the current detection device, the magnetic flux density of a measurement area is enhanced through the soft magnetic element covering the surface of the conductor, the sensitivity and the signal-to-noise ratio of current measurement are improved, and the advantages of reducing alternating-current frequency, position errors, stray magnetic field influences and the like are brought. 本公开涉及一种电流检测装置、功率模块和用电设备,该电流检测装置包括电流感测元件和软磁元件。电流感测元件用于在第二方向
