Abstract

An intelligent power module comprises an IGBT and an intelligent circuit. The IGBT is connected with the intelligent circuit. The intelligent circuit includes an external interface (10), a master controller (20), a drive circuit (30), a protection circuit (40) and a temperature sensor (50), wherein the external interface (10) is connected with the master controller (20), and the drive circuit (30), the protection circuit (40) and the temperature sensor (50) are respectively connected with the master controller (20); the master controller (20) is used for supplying working signals to the drive circuit (30) and receiving IGBT abnormal information fed back by the protection circuit (40), and the master controller (20) is further used for communication with a master control system of a user. The drive circuit (30) is connected with the IGBT and used for charging and discharging a grid electrode for the IGBT. The protection circuit (40) is connected with the IGBT and used for providing circuit protection for the IGBT. The temperature sensor (50) is used for detecting the temperature of the intelligent power module during the working process and feeding back the temperature to the master controller (20).

Description
