摘要： The present invention relates to an uninterruptible power supply, more specifically, to an uninterruptible power supply for the backup of AC-power supply which comprises an electric double layer capacitor as an energy storage device. The uninterruptible power supply according to the present invention comprises an AC power source, a AC/DC converter which converts an AC input from the AC power source into an DC power, an energy storage device which stores an extra electric energy and a DC/AC inverter which converts DC input from the energy storage device into AC power and supplies the AC power to an output load at a power interruption, wherein the energy storage device is an electric double layer capacitor and a ratio of charging voltage of the electric double layer capacitor to a minimum operating voltage of the DC/AC inverter is adjusted to 1.3 times or higher. The uninterruptible power supply has highly enhanced energy efficiency and power backup time, compared even to the conventional DC power backup system such that efficient power backup can be achieved.
摘要翻译：本发明涉及一种不间断电源，更具体地说，涉及一种用于备用AC电源的不间断电源，该电源包括作为能量存储装置的双电层电容器。根据本发明的不间断电源包括AC电源，将来自AC电源的AC输入转换为DC电力的AC / DC转换器，存储额外电能的能量存储装置和DC / AC 逆变器，其将来自能量存储装置的直流输入转换为交流电力，并且在电力中断时将交流电力提供给输出负载，其中所述能量存储装置是双电层电容器，并且所述双电层电容器的充电电压的比率将DC / AC逆变器的最小工作电压调整到1.3倍以上。不间断电源具有高度的能源效率和电力备份时间，与传统的直流电源备份系统相比，可以实现高效的电源备份。
