【摘要】 从功率因数校正电路特点入手，建立了用于大信号分析的ＴＬ域准稳态近似模型，并依此对闭环系统的Ｌｙａｐｕｎｏｖ稳定性进行分析，得出为保证大范围渐近稳定性的恰当反馈函数。最后，依据ＴＬ域准稳态近似模型的计算机模拟与实验结果吻合，验证了模型的正确性。更多还原

【Abstract】 In this poper, a kind of large signal model for power factor cprrection-TL domain quasistationary model is presented.Based on the model, the full closed loop system’s Lyapunov stability is analyzed.The large region asymptotic stability can be reached with correct selection of feedback function. The detailed simulation of the system with the model and its transformation to Ts domain are provided. Experimental oscillograms are also provided for verification.更多还原
