Development And Application Of DC Power Supply Based On Supercapacitor

As a new kind of energy storage component, supercapacitors have fast response, high charge-discharge effciency, and there are types of commodities on sale which speedup assemble and facilitate to enlarge energy storage capacity, therefore the supercapacitor is considered the most promising energy storage device. Supercapacitor dc energy storage system is the key device of the supercapacitor energy storage system. It plays an important role on improving efficiency and reliability of supercapacitor energy storage system. In conclusion, based on some important aspects of Supercapacitor energy storage unit application and design, the equivalent model of directly paralleled supercapacitor/Battery hybrid was set up and the performance and its influence factors were analyzed quantificationally with pulsant load as an example. As supercapacitor use in dc power supply, two programme were put forward for the dc power supply, one is based on supercapacitor sole storage, the other is based on supercapacitor/Battery hybid energy storage. which have theory and practical meanings to provide optional scheme to the project applications.
