STMicroelectronics has announced it is supplying its third-generation silicon-carbide (SiC) MOSFET technology for the e-compressor controllers from ZINSIGHT Technology, a Chinese high-tech company focusing on SiC power modules and advanced electric power conversion systems, for new energy vehicles (NEVs). These highly efficient controllers offer several benefits including an extended electric vehicle (EV) driving range of 5~10km (for a medium-size EV model with battery capacity from 60 kWh to 90 kWh) that is particularly beneficial during the summer and winter seasons.
ZINSIGHT is the only company in the world today that mass-produces SiC based e-compressor controllers for air-conditioning running on 400V, 800V and 1000V EV platforms, delivering a significant number of units by the end of 2023. ST’s advanced third-generation 1200V SiC MOSFET ensures industry-leading process stability and performance, efficiency, and reliability. The EV e-compressor controllers use ST’s third-generation SiC MOSFET technology in combination with ZINSIGHT’s unique cooling solution and advanced thermal protection design. Together the e-compressor controllers deliver better thermal management for NEVs, improved NVH (noise, vibration, and harshness), and greater compactness and cost efficiency for e-compressors. For example, without compromising summer and winter mileage, this solution can help carmakers achieve significant cost saving per EV in overall system expenses.
