Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] The present invention provides an intelligent power module.

[0039] Intelligent Power Module, IPM (Intelligent Power Module), is a power drive product that combines power electronics and integrated circuit technology. The intelligent power module integrates the power switching device and the high-voltage drive circuit, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the...

Abstract

The invention discloses an intelligent power module and an air conditioner. The intelligent power module comprises a shell, three-phase low-voltage driving power modules, three-phase high-voltage driving power modules and braking circuit modules, wherein the three-phase low-voltage driving power modules, the three-phase high-voltage driving power modules and braking circuit modules are arranged inthe shell; the three-phase low-voltage driving power modules and the three-phase high-voltage driving power modules are mutually arranged at intervals; the braking circuit modules and the three-phasehigh-voltage driving power modules are mutually arranged at intervals; and the three-phase high-voltage driving power modules are mutually arranged at intervals. By using the intelligent power module, electrical noise on a high-voltage side or the possibility that pulses escape back from an upper bridge power device and a lower bridge power device to the low-voltage driving modules on a low-voltage side is reduced.

Description

technical field [0001] The invention relates to the technical field of electronic circuits, in particular to an intelligent power module and an air conditioner. Background technique [0002] The intelligent power module is provided with a high-voltage drive circuit, a low-voltage drive circuit, and an upper bridge arm switch tube and a lower bridge arm switch tube. The gate of the switch is connected to the driving circuit, the collector of the switch is coupled to a high voltage, and the emitter of the switch is coupled to the load. The intelligent power module usually integrates the drive circuit of the low-voltage side and the drive circuit of the high-voltage side into one chip, and the upper-arm switch tube and the lower-arm switch tube are assembled on the same carrier by soldering, such as a substrate. However, when the high voltage VH is greater than 1200V, this assembly method does not meet the isolation requirement between the high voltage side and the low voltage...
