摘要
对分段式PWM控制技术在变频调速系统中的应用进行了讨论,通过研究逆变器上下桥臂的PWM信号之间的时间差对系统性能的影响,给出了解决的思路,提出了一套实用的补偿算法,仿真实验和实际应用表明该方法在高速和低速下均具有较好的动态和稳态性能。
This paper introduces a sub-PWM control technology in the speed control system. The effect of the time difference between the upper and lower bridge of the inverter on system performance is discussed and a practical compensation algorithm is proposed. Simulation and practical application show that the method has good dynamic and static performance both in high-speed and low-speed.
