汽车安全与防盗最初的电子化开始于1994年的引擎防盗(IMMO)，恩智浦半 导体(当时的飞利浦半导体)作为第一家半导体公司把RFID的电子标签技术成功 的应用于汽车电子引擎锁：通过汽车与钥匙间的125kHz的无线通讯实现电子身 份识别，来判断启动汽车引擎。这一技术极大的提高了汽车的安全性，很快就在 欧洲以及北美地区广泛应用，并在短短几年时间内使欧洲的汽车失窃率大幅降低 了90 ，因而成为整个欧洲的汽车标准配置(Automotive safety and anti-theft electronic originally began in 1994, engine anti-theft (IMMO), NXP (then Philips Semiconductors) as the first semiconductor company to RFID electronic tag technology successfully used in automotive electronic engine lock: By car keys between 125kHz and wireless communications for electronic identification, to determine start the car engine. This technology greatly improves the car' s safety, soon in Europe and North America, widely used, and in a few years time so that European auto theft rate significantly reduced by 90 , and thus the entire European automotive Standard configuration)

提出了一种无电流传感器的三相 PWM 整流器控制策略。系统采用双闭环控制，外环 PI 调节器控制直流侧输出电压，内环通过滞环调节器控制有功功率和无功功率，达到单位功率因 数运行的目的。根据整流器的数学模型通过电流重构可获得网侧电流，以实现无电流传感器控制。 仿真实验证明该方案具有良好的控制性能。(In this paper a current sensorless control strategy of three-phase PWM rectifiers is presented. Double close-loop control method is applied in the system. DC voltage is regulated by the external loop PI regulator. The system can operate at unity power factor by controlling the active and reactive power with two inner loop hysteresis controllers. The input AC current can be reconstructed the mathematical model of PWM rectifiers in order to eliminating current sensors . The simulation results prove that the system has good performance.)
