Abstract:
1. A power supply system, comprising: a plurality of electrical loads; a power supply unit being configured for providing power for the electrical loads; and a sequence circuit powered by the power supply unit, the sequence circuit being configured for selectively powering the electrical loads; wherein when failures happen in any one of the electrical loads, the sequence circuit will record the failure, shut down and lock the power supply unit for preventing the power supply unit to continue to power the electrical loads; wherein the sequence circuit comprises a control module and a plurality of switch units, the switch units are connected between the power supply unit and the electrical loads, and the control module is configured for controlling statuses of the switch units; and wherein the sequence circuit further comprises a memory unit, the memory unit stores a first data when the electrical loads are in normal condition and stores a second data when failures happen in any one of the electrical loads, when the power supply system start, the control module first detect the data stored in the memory unit, if the memory unit has stored the first data, the control module will turn on the switch units to provide power for the electric loads, if the memory unit has stored the second data, the control module will shut down the power supply unit.
