Abstract :
The auxiliary power supply for the solar array regulator of low earth orbit satellite is proposed in this paper. It consists of a voltage regulator with two power sources and over-current and low-voltage protection circuits. Two power sources are necessary for the fault-tolerant operation of solar array regulator and protection circuits prevents the propagation of anomaly. The function of proposed auxiliary power supply is verified by simulation.
