摘要

本文利用状态空间平均技术设计了有源箝位正变换器的小信号离散时间模型,并考虑了控制回路中的调制器效应和时延。采用数字再设计方法对有源箝位正激变换器进行MATLAB仿真,验证了所设计模型的有效性和补偿效果。最后给出了采用离散时间控制器的5V、100W有源箝位正激变换器的仿真结果并进行了分析。

Digitally controlled Active Clamp Forward Converter with small signal discrete-time modeling
In this paper the Small Signal Discrete-time Model for Active Clamp Forward Converter is proposed by using state space averaging technique to design a digital controller, takes in to consideration of modulator effects and delays in the control loop. The validity of the designed model and achievement of desired compensation for Active Clamp Forward Converter with digital controller is confirmed by the results of the MATLAB simulation by using digital redesign method. Finally simulation results are presented and analyzed for 5V, 100W Active Clamp Forward Converter with Discrete-time controller.
