一、 概述 I. Overview
目前我国发电厂和变电站正在大规模改造直流系统的电源设备，过去采
用的相控电源和磁饱和式电源存在稳压、稳流精度差、纹波系数大及对输入电网谐波污染大等缺点，已经不能满足我国电力工程发展的需要。而被体积小、重量轻效率高、噪声小、稳压稳流精度高、响应速度快的高频开关电源逐步取代，并且可以方便的实现“四遥”功能和N+1冗余备份，使得电力直流系统运行更可靠。JZ高频开关电源模块是集九洲公司多年开发生产经验，为电力直流系统开发的高科技产品，满足现代电力市场的需求。
At present, the power generation plants and substations in our nation are reconstructing the power equipments for DC system in large scale. The phase-controlled power and magnetic saturated power adopted in the past have the defects of low precision of steady voltage and constant current, large ripple coefficient and more pollution to harmonic input to the grid, which cannot meet the development needs of the power engineering in our nation and are replaced by the high-frequency power with switch and small volume, light weight, high efficiency, less noise, high precision of steady voltage and constant current and rapid response speed. This kind of power can realize the function of “four-remote” and N+1 redundancy backup conveniently, which makes the DC system of electric power more reliable. JZ high-frequency Switch Power-Supply Module is a high-tech product developed for the DC system of electric power by Jiuzhou Company based on several-year experience in development and production, which can meet the demands of modern electric power market.
二、 工作原理 II. Working principle
JZ高频开关电源模块采用了先进的无源PFC技术和脉宽调制软开关技
术的控制技术（PWM），使得模块效率进一步提高，谐波减小。模块采用交流三相三线制380VAC平衡输入方式，不存在中线电流损耗。模块交流输入经过尖峰抑制电路和EMI吸收电路，经全桥整流滤波电路将三相交流电压整流为脉动的直流电压，由高频脉宽调制变换器变换将脉动的直流电压成高频方波电压，再由输出整流滤波电路，得到稳定的输出电压和电流，在电网电压和负载发生变化时反馈调整电路控制脉宽调制电路，使得输出电压和电流保持稳定。

and makes the harmonic reduce. The module adopts balance input way of AC three-phase and three-wire 380VAC, which has no current loss in neutral conductor. The AC input of the module passes through spike suppression circuit and EMI snubber circuit and rectifies the three-phase AC voltage into pulsatile DC voltage through full-bridge rectifier and filter circuit. Then the high-frequency pulse-width modulated converter converts the pulsatile DC voltage into high-frequency square-wave voltage and then outputs rectifier and filter circuit, totally through which the stable output voltage and current are obtained. When the voltage and load of the grid change, the control pulse width of the feedback and regulating circuit will modulate the circuit to make the output voltage and current maintain stable.
