Abstract

The present application discloses an electric appliance, a power device, and a method for forming the same. The power device comprises a substrate; first to third upper bridge arm switch tubes, firstto third lower bridge arm switch tubes, first to third upper bridge arm high-voltage drivers, first to third lower bridge arm low-voltage drivers, and a PFC circuit which are disposed on a first sideof the substrate, wherein the first to third upper bridge arm high-voltage drivers are connected to the first to third upper bridge arm switch tubes respectively; the first to third lower bridge arm low-voltage drivers are connected to the first to third lower bridge arm switch tubes respectively; the first to third upper bridge arm high-voltage drivers are manufactured by a BCD or SOI process; the first to third lower bridge arm low-voltage drivers are manufactured by a BIPOLAR or COMS process. The introduction of high and low voltage drivers minimizes the area of the power device body and improves the usability and the reliability of the power device without increasing the overall solution cost.

Description

technical field [0001] The present application relates to the technical field of power devices, in particular to a power device, a method for forming a power device, and an electrical appliance. Background technique [0002] Intelligent Power Module, or IPM (Intelligent Power Module), is a power drive product (power device) that combines power electronics and integrated circuit technology. The intelligent power module integrates the power switching device and the high-voltage driving circuit, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the intelligent power module receives the control signal from the MCU (Micro Controller Unit, micro control unit) to drive the subsequent circuit to work, and on the other hand, it sends the system status detection signal back to the MCU. Compared with traditional discrete solutions, intelligent power modules have won an increasing market due to their advantages of high integrat...
