Abstract

Abstract

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.
