摘要
分析了串联型逆变器频率跟踪电路的电路参数对逆变器运行的稳定性和动态性能的影响,提出了一种简单实用的变带宽电荷泵锁相环逆变控制方法,对其稳定性和动态响应能力进行了理论分析和仿真验证。仿真结果显示,该方法可以大大提高逆变器频率跟踪速度,并且不会影响环路正常工作时的稳态误差和噪声抑制性能。
This paper analyzes the influence of control circuit parameters to stability and dynamic characteristics of series resonant inverter, and proposes a simple variable frequency-bandwidth CPPLL frequency tracking circuit. The simulation results demonstrate that the theoretical analyses are correct, and the proposed control circuit can increase the frequency tracking speed of series resonant inverter greatly and has not negative inferences to the normal performance of series resonant inverter .The conclusions will benefit to design control circuit of resonant inverter and have reference values to other implementations with PLL, too.
