摘要
为了降低高压变压器中匝数比过大带来的影响,业界普遍采用变压器加倍压整流电路的多级升压方式实现高电压输出.本文通过研究对称反向高压倍加器(Cockcroft-Walton accelerator,CW)型倍压整流电路的工作原理,分析了输入电压频率、负载和电容值对对称反向CW型倍压整流电路输出电压压降和输出电压纹波的影响.研究发现该电路适用于高频率输入电压、轻负载、大容值电容的工作场景,可以根据确定的输入电压、输出电压、以及负载大小等参数,来选择合适的电压频率和电容,使得输出电压压降和输出电压纹波达到最小.
Abstract
In order to reduce the influence of too large turn ratio in high voltage transformer,the multistage boost mode of transformer voltage doubling rectifier circuit is widely used in the industry to achieve high voltage output. By studying the working principle of symmetrical reverse Cockcroft-Walton accelerator ( CW) type voltage doubling rectifier circuit,the influences of input voltage frequency,load and capacitance on output voltage drop and output voltage ripple of symmetrical reverse CW type voltage doubling rectifier circuit are analyzed in this paper. It is found that the circuit is suitable for high frequency input voltage,light load and large capacitance. The appropriate voltage frequency and capacitance can be selected according to the determined input voltage,output voltage,and load size parameters,so that the output voltage drop and output voltage ripple are minimized.
