摘要： A power supply control system includes a power supply unit, a timing sequence controller, at least one converting circuit, and a power managing controller. The power supply unit provides a direct current input voltage. The timing sequence controller is powered by the power supply unit. The at least one converting circuit converts the input voltage into a direct current working voltage. The managing controller includes a detection unit detecting a voltage value of the output port, a comparison unit for comparing the voltage value of the output port with a value of the input voltage, and a control unit switching off the power supply unit when the voltage value of the output port is equal to value of the input voltage.

摘要： A buck converter includes an input terminal, two MOSFETs, a PWM module and a control module. The input terminal is coupled to a power source to provide power to the buck converter. The PWM module is coupled to the gates of the two MOSFETs to alternately turn on and turn off the two MOSFETs. The control module is configured to shut down the power source if a drain-source resistance or a gate-source resistance in either one of the two MOSFETs is not within normal values when the two MOSFETs are turned off.

摘要： A power supply system includes a power supply unit, a number of electrical loads and a sequence circuit. The power supply unit provides power for the electrical loads through the sequence circuit. When any one of the electrical loads fails the sequence circuit will record the failure, shut down and lock the power supply unit to prevent the power supply unit from powering the electrical loads.

摘要： A power protection circuit includes a fuse, a plurality of voltage converters, and controller. The fuse is electrically connected to a power source to transfer electric energy. The controller controls the fuse and the voltage converters, and the voltage converters are selectably electrically connected to or disconnected from the power source through the fuse. When the output voltage of a voltage converter exceeds a predetermined voltage of the voltage converter, the controller blows the fuse to the voltage converters. Hence, a computer cannot be restarted immediately before troubleshooting and replacement of the blown fuse, which can protect the voltage converters and the adjacent components in the computer due to direct reboot.
