Qingjia Electronics
Recommended for:Qingjia Electronics - a professional automotive connector and power semiconductor (IGBT single tube, IGBT module, silicon carbide SiC-MOSFET, gallium nitride GaN, driver IC) distributor, focusing on the three major directions of new energy, transportation electrification, and digital transformation. Committed to serving China's industrial power supply, power electronic equipment and new energy vehicle industry chain. Compared with traditional cars, new energy vehicles have a greater increase in the number of electric drive units and electrical equipment. The internal power current and information current are intricate, especially the high-current, high-voltage electric drive system, which affects the reliability of the connector. , volume and electrical performance have put forward higher requirements, which means that the demand and quality requirements for connector products in new energy vehicles will increase significantly. In new energy vehicles, high-voltage connectors are extremely important components and are used in both complete vehicles and charging facilities. The main application scenarios of high-voltage connectors on the entire vehicle include: DC, water heating PTC charger, air heating PTC, DC charging port, power motor, high-voltage wiring harness, maintenance switch, inverter, power battery, high-voltage box, electric air conditioner, AC charging Mouth etc. In electric vehicles, the application of silicon carbide power devices is mainly in two directions, one is used for motor drive inverter (motor controller), and the other is used for vehicle power supply system, mainly including: power conversion system (vehicle DC/DC ), on-board charging system (OBC), on-board air conditioning system (PTC and air compressor), etc. Decarbonization has become a trend in the industry. Under my country's dual-carbon policy, that is, "carbon peaking and carbon neutrality." New energy, new infrastructure, and photovoltaic power generation have gradually become the focus of attention. Qingjia Electronics continues to provide high-quality power semiconductor new energy automotive connectors in new energy vehicle electronic controls, charging piles, automotive OBC, new energy power generation, and industrial and commercial energy storage. In-depth cooperation with customers in the fields of converters, electric vehicle motor main drives, photovoltaic inverters, energy storage converters PCS, industrial power supplies, etc., continues to serve customers' supply chains and new product development, and fully supports China's new energy vehicles and electric power Electronic industry development!
