【摘要】 随着工业和科学技术的快速发展,高层建筑、医院以及工厂等公共设施对供电的要求将越来越高,一旦中断供电,将造成重大的事故或经济损失。与EPS(Emergency Power Supply)相比而言,UPS(Uninterrupt Power System)除了需具有对负载不间断供电的能力之外,还需要对输入的市电进行稳压、滤波处理,来得到较高质量的电力输出,通常适用于对计算机、通信设备、网络设备等精密仪器的电力供应,以确保设备运行过程中的数据安全,其制作成本较高;而EPS不需要对市电进行稳压,一般用于对电能质量要求不高的设备,在市电故障时,作为应急电源供负载使用,对系统的可靠性要求较高,其成本相对低廉。本文的研究工作主要围绕逆变电路、充电环节的设计和电池监测单元的研制三个方面展开。首先,在调研了国内外逆变开关电源技术研究的现状及应用技术的基础上,对当前国内外应急电源进行系统的分析和综合,针对用户提出的应急电源技术指标,设计应急电源系统总体方案以及逆变器的主电路,计算功率变换器参数以及确定IGBT的选型。其次,本文依据免维护密封铅酸蓄电池的充电和消防用应急电源的要更多还原

【Abstract】 With the rapid developing of industry and modern science and technology, such communal facilities as the skyscraper, hospital and factory, etc. will be higher and higher to the demand for supplying power. Compared with EPS(Emergency Power Supply), UPS(Uninterrupt Power System) has the capability of providing uninterruptible power for load, furthermore, to get high quality power of output voltage, it has to deal with the input power, such as stabilizing voltage, filtering ripple, etc. It usually applies to the power provision of precise apparatus like computer, communication equipment and network equipment, etc. as a result, the cost of UPS is higher relatively. While it needs not stabilize the input power, EPS usually fits for the load which does not require high quality power. When the input power is abnormal, it can be used as emergency power. Generally, the requirement of EPS’s reliability is high and the cost is low comparatively.This paper mainly studies about implementation of inversion circuit,更多还原
