FORMOSAT-5 Satellite Power Protection Design

Abstract:

The main functions of the Power Control and Distribution Unit (PCDU) in FORMOSAT-5 satellite are to condition energy from the solar arrays and distribute power for all subsystems on the satellite. The Power Relay (PR) module, one of the major modules in the PCDU is to manage the switchover of redundant DC-DC converter sections, secondary power distribution and power protections. The PR module controls power protections which are under voltage (UV) protection and Undervoltage-Lockout (UVLO) detection. UVLO detection monitors primary power voltage with majority voting in PR FPGA. UV detector switches nominal DC-DC converter to redundant DC-DC section, when under voltage happens. Power protection circuits all can be realized by Inverting Bistable Multivibrator. This paper describes protection methods for power and the reliable circuit design implementation.
