The invention relates to the technical field of vehicle-mounted air conditioners, in particular to a compressor driving circuit, a control method and a vehicle-mounted air conditioning system. According to the circuit, when an engine of a vehicle is turned off, a storage battery is used for outputting direct current to an inverter when a first relay is turned on; the inverter is used for receivingthe direct current, inverting the direct current to generate alternating current and outputting the alternating current to a transformer; the transformer is used for receiving the alternating currentand carrying out voltage transformation on the alternating current; and the transformer is also used for outputting the alternating current subjected to voltage transformation to a compressor so as to drive the compressor to work. Through the circuit, under the condition that the engine is not started, the direct current of the storage battery can be converted into the alternating current to supply power to the air conditioner compressor, the noise of using a vehicle-mounted air conditioner during parking is reduced, the energy consumption and the engine loss of a vehicle are reduced, the service life of the vehicle is prolonged, and the vehicle use experience of a user is improved.

    本发明涉及车载空调技术领域,尤其涉及一种压缩机驱动电路、控制方法及车载空调系统。所述电路包括:在车辆的发动机关闭时,所述蓄电池,用于在所述第一继电器闭合时,向逆变器输出直流电;所述逆变器,用于接收所述直流电并对所述直流电进行逆变以生成交流电,并将所述交流电输出至所述变压器;所述变压器,用于接收所述交流电,并对所述交流电进行变压;所述变压器,还用于将变压后的交流电输出至所述压缩机,以驱动所述压缩机工作。通过上述电路,使得在发动机未启动的情况下,也能够通过将蓄电池的直流电转换为交流电为空调压缩机供电,降低了停车时使用车载空调的噪音,降低了车辆的能耗与发动机损耗,延长车辆寿命,提升用户用车体验。
