一、概述Summarization

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-22010C型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。 Nowadays, power plants and transformer substations are reforming DC system power-supply equipments in our country. The phase-modulated and magnetism-saturation power-supplies have many disadvantages including low precision in stabilizing voltage or current, high ripple coefficient, heavy pollution of harmonic to input electric network, etc. and cannot meet the demands of the development of our electric power engineering. With low noise, high precision in equalizing voltage or current, and high speed of responding, the little and light high-frequency switch power-supply has been popular by and by. It can perform the “four remote” functions and setup N+1 redundancy backup conveniently, which make electric power DC system running more safely. JZ-22010C high-frequency switch power-supply module is high-tech product developed by Jiuzhou Co. for electric power DC system to meet the demands of modern electric power market with its years of production experience.

二、工作原理Mechanism

JZ-22010C型高频开关电源模块采用了全桥移相式脉宽调制软开关控制技术，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，由高频全桥移相式脉宽调制变换器将脉动的直流电压变换成高频方波电压，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移相脉宽调制电路，使得输出电压和电流保持稳定。

JZ-22010C high-frequency switch power-supply module is produced with the advanced techniques of full-bridge phase-shifting PWM soft switch control. Its efficiency is enhanced and its harmonic is minished. The module inputs current with the equilibrium AC ternary-phase 3-line 380VAC so that there is no wastage in middle line. It input current through peak-restricting circuitry and EMI absorber circuit, and full bridge rectifier-filter circuit which change the ternary-phase AC voltage into pulsed DC voltage, then trough high-frequency full-bridge phase-shifting PWM which change the pulsed DC voltage into high-frequency quadrate-wave voltage. At last, through output rectifier-filter circuit, the stabilized voltage and current is outputted. Even when the electric network’ voltage and load change, the voltage and current can keep stable because the feedback-modulating circuit control phase-shifting PWM circuit.
