摘要

高压脉冲电容器充电电源是强激光能源系统的重要组成部分

而串联谐振式高压电容器充电电源是其中的一种典型拓扑结构。充电效率是反映电容器充电电源工作特性的一个重要指标。提高充电电源的效率既是高效用电的要求

也是保证充电速度、设备安全和电磁兼容性的需要。变流环节损耗、谐振环节损耗、升压环节损耗、谐波畸变功率损耗和"T"形回路损耗等是其主要的损耗来源。因此

采用软开关技术、提高功率因数、减小谐波畸变、合理设计变压器和"T"形回路等是提高效率的主要措施。分析和试验表明

采用有关措施后

效率显著提高

整机效率达87%

同时

也促进了其他运行特性的改善。

Abstract

The efficiency of capacitor charging power supply（CCPS） is an important index in high power laser energy system

and the series resonant type high voltage capacitor charging power supply is one of these typical power supply. Improving the efficiency is not only the demand for efficient using of power energy

but also the necessity for insuring the charging rate

device safety and electromagnetic compatibility.The power loss of inverter

LC resonance

voltage rising

harmonic distortion

and the "T" shaped loop loss is the main parts of loss. So the measurement of soft-switching

improving power factor

reducing total harmonic distortion（THD） of harmonics

rational designing of the transformer and the "T" shaped loop must be taken to decrease the power energy loss. Analysis and test show that efficiency is raised by using the relevant measures

the whole efficiency is more than 87%

and other performances are also improved.
