摘要
现代通信系统对供电系统的要求越来越高,传统的UPS系统已无法满足日益发展的通信系统需求,240 V直流供电系统以其较高的可靠性将逐渐发展成为UPS系统的完美替代品。文中比较了UPS与240 V直流供电系统的特点,对240 V直流供电系统的原理和拓扑结构进行了分析,通过分析比较得出240 V高压直流供电系统的可行性和可推广性。
Power supply for modern communication system is required more and more strictly.The traditional UPS system has been unable to meet the development of the communication system.The UPS system will gradually be replaced by 240 V DC power supply system which has high reliability.In this thesis,characteristics of the UPS were compared with those of 240 V DC power supply system,and the principle and the topology structure of 240 V direct current power supply system were analyzed.Through the comparison and analysis,conclusion of the feasibility and extension of 240 V high voltage DC power supply system is given.
