Research of the Crane System Based on Technology of Storing-Energy with Super-capacitor

Saving energy, lowering energy consumption and reducing pollutants discharge was an important factor of effecting economic development. This is a new research direction to use super capacity to crane system. In this paper, the character of the super capacitor was firstly introduced and analyzed. Secondly, the DC-DC converter used in crane system based on mix power was designed. And the technology of soft switch was discussed. Then the calculating method of super capacitor was described.
