Embodiment Construction
[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0038] The invention provides an intelligent power module.
[0039] Intelligent Power Module, or 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 driving circuit, and has built-in fault detection circuits such as overvoltage, overcurrent and overheating. On the one hand, the intelligent pow...

The invention discloses an intelligent power module and an air conditioner. The intelligent power module comprises: a casing; a three-phase low-voltage drive power module, a three-phase high-voltage drive power module and a brake circuit module, a three-phase low-voltage drive power module, The three-phase high-voltage driving power module and the braking circuit module are arranged in the casing; the three-phase low-voltage driving power module and the three-phase high-voltage driving power module are arranged at intervals from each other, and the braking circuit module and the three-phase high-voltage driving power module They are spaced apart from each other; the three-phase high-voltage drive power modules are spaced apart from each other. The present invention reduces the possibility that electrical noise or pulses on the high-voltage side travel back from the upper-bridge power device and the lower-bridge power device to the low-voltage driving module on the low-voltage side.
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 a switch tube of the upper bridge arm and a switch tube of the lower bridge arm. The gate of the switch tube is connected to the drive circuit, the collector of the switch tube is coupled to a high voltage, and the emitter of the switch tube is coupled to a load. The intelligent power module usually integrates the driving circuit of the low-voltage side and the driving circuit of the high-voltage side into one chip, and the upper-side switching tube and the lower-side switching tube are assembled on the same carrier, such as a substrate, by soldering. However, when the high voltage VH is greater than 1200V, this assembly method does not meet the isolation requirements between the...
