  • Patent number: 9996134
    Abstract: A method to avoid over-rebooting of a power supply device comprises Step 1: receiving a power-good signal generated by a power supply device working normally; Step 2: checking whether the power-good signal is received; if no, demanding the power supply device to reboot; and Step 3: recording a count of rebootings of the power supply device; after the power supply device reboots, checking again whether the power-good signal is received; if yes, letting the power supply device keep on working and resetting the count of rebootings; if no, demanding the power supply device to reboot again, accumulating the count of rebootings, and checking whether the count of rebootings is greater than a limited count of rebootings; if yes, forbidding the power supply device to reboot. Thus is solved the problem that a power supply device whose abnormality cannot be removed by rebooting may damage the information device.

  • Publication number: 20170308139
    Abstract: A damage identification method for a redundant power supply system is disclosed. The redundant power supply system comprises a plurality of power supply devices and a control unit. In application of the method, the control unit respectively sends switching signals to the power supply devices to boot every power supply device. The control unit checks whether each of the power supply devices sends back a power state signal. If at least one power supply device does not sends back the power state signal, the control unit resends the switching signal to the power supply device to compulsorily reboot the power supply device, which does not output the power state signal. Thereby is solved the problem that the conventional technology cannot instantly exclude temporary abnormalities and causes the user to misjudge the failure of a power supply device.

  • Publication number: 20170269941
    Abstract: A method for forcibly resetting a microcontroller is provided. A switching module is provided to power a microcontroller. The switching module detects through the control pin whether a notification port of a load connected to the control pin changes its potential level in response to a communication error between the load and the microcontroller detected by the load. When the switching module learns the change in the potential level of the notification pin, a powering status of the switching module is switched to stop powering the microcontroller to cause the microcontroller to stop operating. It is detected through the control pin whether the load again changes the potential level of the notification port in response to the microcontroller having stopped operating. When the change is detected, the powering status of the switching module is switched to again power and reactivate the microcontroller.

  • Publication number: 20150286274
    Abstract: A power supply device with reduced power consumption is electrically connected to a motherboard. The motherboard outputs a power-on signal or a power-off signal to the power supply device when being triggered. The power supply device includes a standby power supply module which modulates an external power to output a standby power. Upon receiving the power-on signal, the power supply device deactivates the standby power supply module, but activates a main power supply module to modulate the external power to output an operating power to the motherboard to replace the standby power. Upon receiving the power-off signal, the power supply device deactivates the main power supply module, but reactivates the standby power supply module so that the standby power supply module outputs the standby power to the motherboard.
