A CubeSat size class "HIT-SAT" is a micro satellite that developed by Hokkaido CubeSat development team. Its volume and weight is 2.7kg and 12cm cubed. It was fixed in the sub payload space of M-V-7, and was ejected after main satellite separation on September 23, 2006. The orbit is sun-synchronous orbit of the altitude of 279-660 [km] and the inclination of 98.32 [deg]. The purpose is to examine some functions of the bus system. This research report describes an electric al power subsystem design. The major difficulty of Electrical Power System is surely OFF and ON. The OFF needs to be guaranteed to power down in launching rocket. The ON needs to be guaranteed to power up in starting HIT-SAT after separated from rocket. The positive operation of this was the important demand of M-V-7 and HIT-SAT. In addition, HIT-SAT has many of commercial-the products. Therefore, HIT-SAT should increase the margins of the application for safety.
