| Popis: | Electric Vehicle / Hybrid-Electric Vehicle (EV/HEV) technologies are becoming increasingly important for realizing fuel-efficient vehicles. In particular, maximizing the energy efficiency of motors, while enhancing power and speed requires high-performance semiconductor devices, such as microcontrollers (MCU) and power devices. However, high-performance MCUs suitable for EV/HEV applications have yet to be reported, while attractive power devices, such as SiC devices, are becoming commonplace [1]. In this paper, we have designed an MCU architecture with intelligent motor-timer system (IMTS), including 0.8µs high-speed field-oriented-control (FOC) processing and an angle-tuning circuit (ATC). We have also designed a functional safety mechanism essential for automotive use [2]. |
