摘要
分析了一种基于现场可编程逻辑器件(FPGA)的谐振型逆变器控制电路,在FPGA芯片上实现了自采样比例积分(PI)控制全数字锁相环(ADPLL)的设计。采用了自采样比例积分的策略,使锁相环在不同的锁频点具有几乎相同形式的传递函数,有利于理论分析和环路设计。理论分析、仿真验证和试验结果都表明该逆变器控制电路具有环路参数设计简单、频率跟踪范围广、跟踪速度快、系统稳定性好、控制灵活等优点。
The resonant inverter control circuit based on field programmable gate array (FPGA) device is analyzed. The design of self-sampling PI control all digital phase-locked loop (ADPLL) is implemented on the FPGA chip.The transfer function as linear approximation of the system model remains almost the same at different took point. The static and dynamic results of simulation and experiments verify that this inverter's control circuit is feasible.
