摘要：

Proton exchange membrane (PEM) fuel cell uninterrupted power supply (UPS) has been getting much attention recently. Fuel cell UPS needs another bridge power to smooth from the utility to the fuel cell because the fuel cell stack takes a certain time to start up. Batteries play the role conventionally. Ultracapacitor has many advantages compared with batteries excepts a problem: ultracapacitor voltage drops sharply while discharging. This paper studied a dynamic discharge structure model for ultracapacitor application in a 3kW base station UPS. The duration of holding valid voltage by the dynamic discharge structure is more than twice comparing to the static discharge structure. Also the dynamic discharge structure has a better efficiency than the static discharge structure using a DC/DC converter to extend the duration.
