摘要
分析了LCC谐振电源在电流断续模式下的双脉冲输出工作原理,通过数学计算,推导出了电路输出特性,并在此基础之上完成了系统的小信号建模,确定了系统闭环控制模型。通过优化数字PID参数,提高了变换器的输出电压动态调节能力。搭建的1 700 V/200 m A实验室样机验证了除尘器电源控制模型的正确性和补偿器参数设计的合理性,实现了除尘器输出电压的快速调节。
The working principle of double pulses output mode of LCC resonant power supply in DCM is analyzed.The output characteristics of the circuit are derived by mathematical calculations, and the system small signal modelis provided, also the system’s closed-loop control model is given. The dynamic nature of the output voltage of theconverter is improved by the optimized numerical PID configures. The validity of the control model and therationality of the compensator configure design are verified by the 1 700 V/200 mA experimental prototype, and therapid adjustment of the ESP’s output voltage is realized.
