摘要
为了研究电容器放电结束后的能量补充,推进电容器充电电源(CCPS)根据电容器输出电压的要求,对带电阻器的高压直流电源、谐振充电电源和高频变换器充电电源技术进行了讨论,并对其进行了验证和对比。带电阻器的高压直流电源电路简单,但是体积庞大,效率低下,适用于要求不高的场合;谐振充电电源对开关的耐压和电容容量要求很高,调整率很差;高频变换器采用电力电子和现代控制技术,使得充电电源运行起来更安全、可靠、易控,是目前采用的主要技术。另外,因三相谐振充电电源和并联模块充电电源是大功率充电电源的发展方向,故应根据需要选择充电方式和电路结构,以达到更高的性价比。
This paper discusses the output requirements of a capacitor charging power supply. Three techniques which may be utilized to charge capacitors to the specified voltage are examined and compared： high voltage dc power supply with charging resistor has its characteristics, the advantages are its simplicity, reliability, and low cost, the major disadvantage is its poor efficiency; resonance charging power supply requires two high voltage switches; high frequency converter focuses on the application of power electronic technology to capacitor charging power supplies, some of the benefits of this technology are improvement in efficiency and regulation and a reduction in size and weight. High power capacitor charging power supply using three-phase series resonant converter and parallel models is also discussed.
