摘　　要：为使LC谐振充电方案具有更高的升压范围和提高其对供电电压的适应性,采用了一种带有升压结构的电路拓扑,使得LC谐振充电方案具有升压和降压工作能力,同时采用了基于能量实时检测的控制算法,使得该方案能够根据预设参数准确充电和放电,增强了对供电电压波动的适应能力。初步的实验结果表明,在供电电压波动的情况下,该电源能够完成升降压的调节,且最大电压偏差小于5 V。LC resonant charging scheme is suitable for high repetition rate pulse power system because of its simple circuit structure and control method,small size and high power efficiency.To make the LC resonant charging scheme with a higher boost range and improve its adaptability to supply voltage changes,this paper adopts a circuit topology with a boost structure,which enables the LC resonant charging scheme to have the ability to boost and reduce voltage.At the same time,it uses a control algorithm based on real-time energy detection,which enables the scheme to accurately charge and discharge according to preset parameters,and enhances the adaptability to supply voltage fluctuations.The preliminary experimental results show that the power supply can complete the regulation of voltage rise and fall when the supply voltage fluctuates,and the maximum voltage deviation is less than 5 V,thus it has higher charging accuracy and better charging consistency.
