摘要
单周期控制是一种用于功率变换器的新型非线性控制策略,当输入电压发生扰动或负载快速变化时,仅在一个周期内就可实现控制目标。简要分析了单周期控制的控制机理,并在Boost变换器中采用了这种新颖的控制方法用于功率因数校正。基于IR1150研制了一台3kVA的功率因数校正实验样机,给出了设计实例和实验结果。实验结果表明,该变换器的控制方法简单、可靠和通用。
One cycle control is a novel nonlinear control method for power converters. A one cycle controlled switch has the ability to reject the input voltage perturbation or the load step and to realize control objective only one switching cycle. After the analyses of one cycle control mechanism, this method is used in Boost PFC, A 3 kVA PFC Converter is designed based on IRll50 , the design process and experiment results are given. Experimental results prove that the control method of this converter is simple, reliable and general.
