전동압축기electric compressor
본 발명은 전동압축기에 관한 것으로, 더욱 상세하게는, 전기에 의해 구동하여 냉매를 압축시키는 전동압축기에 관한 것이다.The present invention relates to an electric compressor, and more particularly, to an electric compressor driven by electricity to compress a refrigerant.
일반적으로, 압축기란 냉매를 흡입하여 압축한 후 이를 목적하는 곳으로 공급하는 장치를 의미한다. 예를 들어, 차량의 에어컨에 설치되는 압축기는, 증발기로부터 공급받은 냉매를 압축한 후, 응축기로 공급한다. 압축기는 구동 방식에 따라 전동식, 기계식으로 구분된다. 전동식 압축기는 전기의 힘으로 구동되는 모터를 이용하여 냉매를 압축한다. 기계식 압축기는 엔진과 같은 기계의 힘을 이용하여 냉매를 압축한다.In general, a compressor refers to a device that sucks a refrigerant, compresses it, and supplies it to a destination. For example, a compressor installed in an air conditioner of a vehicle compresses the refrigerant supplied from the evaporator and then supplies it to the condenser. Compressors are divided into electric and mechanical types according to the driving method. An electric compressor compresses a refrigerant using a motor driven by electric power. A mechanical compressor compresses a refrigerant by using the force of a machine such as an engine.
그 중, 전동식 압축기는, 모터를 제어하기 위하여 인버터부를 구비한다. 상기 인버터부는, 인버터브라켓 내부에 모터를 제어하기 위한 제어기판을 구비한다. 제어기판은 통신용 저전압부와 전원용 고전압부로 구분되는데, 저전압부에는 통신용으로 대체적으로 부피가 작은 전력소자가 설치되며, 고전압부에는 IPM(Intelligent Power Module), Capacitor, Coil 등 전원용의 대체적으로 부피가 큰 소자가 설치된다.Among them, the electric compressor includes an inverter unit for controlling the motor. The inverter unit includes a control board for controlling the motor inside the inverter bracket. The control board is divided into a low-voltage part for communication and a high-voltage part for power.
