The auxiliary power supply for satellite should make the power safe and support it for subsystems during its operational lifetime. Several contstraints should be required to get high reliability. In this paper, the auxiliary power supply was satisifed and designed to be satisified with some contstraints. Control circuits for the auxiliary power supply used majority voter circuits to remove the single point failure. To verify majority voter circuits, proto-type auxiliary power supply was manufactured and tested.
