Abstract(in English) | Electric double layer capacitors (EDLCs) have many advantages over existing battery technologies from perspectives of life, power capability, and low-temperature performance. However, the main drawback of using EDLCs as a main energy source for spacecrafts is that their voltages vary widely with charging/discharging, whereas output voltage must be supplied in a particular range determined by the load. Since the energy density of EDLC is quite lower than conventional batteries, very efficient energy conversion electronics, with which EDLCs can be discharged as efficiently and deeply as possible to utilize their stored energies, are required. In this paper, a novel spacecraft power system comprising a combination of selective intermediate taps and an unregulated dc-dc converter, with which the EDLCs can discharge very efficiently and deeply, is proposed and verified experimentally. |
