摘　　要：针对我国电气化铁路沿线通信信号、生产生活供电电源存在电压波动幅度大、电压畸变率高造成通信设备故障,UPS设备的负载满足不了铁路信号道岔转辙机等冲击性负荷的要求等问题,研制了基于交直交全波整流、逆变技术的串联型宽电压抗谐波电源装置,显著改善了铁路沿线供电电源的电能质量,保障铁路沿线设备安全可靠供电。With regard to the problems of large voltage fluctuation rate in communication,signal and production and daily power supply along electrified railways in China,the higher rate of voltage fluctuation rate will lead to the failures of communication equipment and lead to the problems that the loads of UPS equipment are unable to meet the requirements of the impact loads from railway signal point machines,a series connected wide voltage anti-harmonic power supply device based on AC-DC-AC technology is developed,it is able to improve dramatically the power quality of power supply devices,ensure the safe and reliable power supply of equipment along the railway line.
