Research And Development Of On-Line Monitoring EPS Emergency Power Supply System

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,...
