摘要

采用CC-PWM开关模型对工作在连续导通模式下的电流编程控制dc - dc SEPIC变换器进行平均大信号和小信号建模。给出了该模型的推导及其在实际5v稳压器性能评估中的应用。预测的仿真结果被负载暂态和稳定条件下的环增益频率响应的测量所证实。

Modeling and performance evaluation of a DC/DC SEPIC converter

The use of the CC-PWM switch model for the average large and small-signal modeling of a current-programmed control DC-to-DC SEPIC converter, operating in the continuous conduction mode is presented. Derivation of the model and its use in the performance evaluation of a practical 5 V regulator are shown. Predicted simulation results are confirmed by measurements for both load transient and the loop-gain frequency response for stability conditions.<>
