Abstract

The invention discloses an intelligent power module and an air conditioner. The intelligent power module includes: a first control signal receiving end and a second control signal receiving end for receiving a control signal output by a main controller; a PFC power switch module, a PFC power switch module It includes a gallium nitride type HEMT tube, the base of the gallium nitride type HEMT tube is connected to the first control signal receiving end; an inverter bridge circuit; and a bridge arm drive circuit, the logic signal input end of the bridge arm drive circuit is connected to the second The control signal receiving end is connected, and multiple output ends of the bridge arm drive circuit are connected one-to-one with the controlled end of the inverter bridge circuit. The invention reduces the volume of the intelligent power module and reduces the occupied area of ​​the intelligent power module on the electric control board.

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, that is, IPM (Intelligent Power Module) wins more and more markets due to its advantages of high integration and high reliability. An intelligent power module is usually integrated with a driver IC and a power device. When working, the driver IC amplifies the logic signal output by the main controller and outputs it to the power device to drive the power device to work. In some highly integrated intelligent power modules, PFC switch tubes may also be integrated. The PFC switch tubes work based on the driver IC, and it is necessary to integrate the corresponding drive circuit in the driver IC, which will increase the size of the smart power module. Contents of the invention [0003] The main purpose of the present invention is to provide an intelligent pow...
