摘要
针对Buck变换器快速动态响应的要求,本文提出了一种具有快速动态响应速度的非线性控制方法——根据负载电流调节的电感电流滞环控制。该方法能够明显改善输入电压及负载变化所引起的动态过程,且物理意义明确、直观,设计过程简单。Matlab分析和仿真结果验证了该控制方法的优越性。
To improve the dynamic response of buck converter.an nonlinear-controller called load-current-regulated inductor current hysteresis controller is proposed. The analysis and Matlab simulation results show that the proposed controller greatly improves the dynamic behavior of buck converler caused by fast variation of input voltage and/or load current, features clear physical meaning and easy design.
