:电流滞环控制具有易于实现、快速的动态响应和无条
件稳定等优点,但该控制方法使逆变器的开关频率不固定,
造成逆变器输出滤波器设计困难,因此很少有文献提及此种
滤波器的设计方法。该文研究了一种基于电流滞环控制的半
桥双降压式逆变器输出滤波器的设计方法。该方法从短路特
性和稳压精度两方面阐述了如何最优选取滤波电感,从谐振
频率和无功补偿两方面阐述了如何最优选取滤波电容-Hysteresis current control method has the

交流伺服系统中的死区效应分析与补偿分析了逆变器的死区效应产生的原因及其对交流伺服系统控制性能产生的影响,指出死区补偿的关键
在于电流相位的获取,为了克服实际系统中电流零点的模糊性,提出了一种基于两相静止坐标系下的前馈死
区补偿方法. 该方法通过对三相输出电流一个周期内补偿电压进行傅里叶变换,发现仅需补偿1 ,5 ,7 次谐波
分量即可消除死区效应. 仿真和试验结果验证了这种方法的正确性和可行性.-AC servo system analysis and compensation of
