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.
Abstract:
A control system capable of controlling activating/deactivating of multiple motherboards via cloud includes a plurality of motherboards, a plurality of power supplies respectively corresponding to the motherboards, a cloud monitoring platform, and a power on/off control module connected to the motherboards and signally electrically connected to the cloud monitoring platform. The cloud monitoring platform includes a graphic control interface, and allows to a user to log in for operations to generate a control signal. After receiving the control signal, the power on/off control module analyzes the control signal to determine to output a trigger signal to at least one of the motherboards. In response to the trigger signal received, the motherboard outputs a power on/off signal to the corresponding power supply connected to turn on or turn of that power supply.
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.
Abstract:
A power supply avoiding over-discharge of battery modules includes a main power supply system and a redundant power supply system. The invention uses a battery protection module to detect the status of a battery module in the redundant power supply system in normal conditions. The battery protection module includes an activation path connected to the main power supply system to receive standby power, a battery detection path connected to the battery module to receive a micro current and generate a protection activation signal when the battery module is in a charge-waiting state, and a protection activation path connected to a switch unit in the redundant power supply system to receive the protection activation signal to make the switch unit enter an OFF state.
Abstract:
A power supply for prolonging a hold-up time includes a main power supply system, and a hold-up power supply system connected in parallel to a power factor correction unit in the main power supply system. The hold-up power supply system includes an isolation transformer element connected to the power factor correction unit for receiving and transforming a first power to a third power, a power storage element for receiving the third power and storing as a hold-up power, and a power comparison unit connected between the power factor correction unit and the power storage element. The power comparison unit compares a second power generated from phase modulation performed by the power factor correction unit and the hold-up power, and outputs the hold-up power when the second power is smaller than the hold-up power, so as to sustain the power modulation unit to continue operating for a hold-up time.
Abstract:
A redundant power supply system providing alternate standby includes at least one primary power supply, at least one secondary power supply and a power integration panel. Each primary power supply receives a first power ON/OFF signal and starts to output a primary duty power. Each secondary power supply receives a second power ON/OFF signal and starts to output a secondary duty power. The power integration panel is electrically connected to the primary power supply and the secondary power supply and has a standby mode to receive a power ON/OFF signal from a motherboard and output alternately at a selected time interval the first power ON/OFF signal to the primary power supply or the second power ON/OFF signal to the secondary power supply to make the primary power supply and the secondary power supply on standby alternately.
Abstract:
A redundant power supply system providing rapid start of backup includes at least one primary power supply, at least one secondary power supply and a power integration panel. The secondary power supply includes a voltage regulation and energy saving element which has regulation potential after the secondary power supply being booted up. When the secondary power supply is triggered to shut down and the regulation potential is lower than a low voltage judgment criterion, it enters a standby working mode in which the secondary power supply is restarted for a transient working period to charge the voltage regulation and energy saving element. The power integration panel is electrically connected to the primary power supply and the secondary power supply, and inspects output status of the primary power supply and the secondary power supply in regular conditions to determine to boot up or shut down the secondary power supply.
Abstract:
A power supply capable of increasing the lifespan of battery modules controls the duty state of a main power supply system through a state switch control module. The state switch control module includes a power supply switch unit and a state switch unit. The power supply switch unit has a first power supply state in which the state switch unit outputs a first signal to allow the main power supply system to output a first power to charge a battery module, and a second power supply state in which the state switch unit outputs a second signal to allow the main power supply system to stop outputting the first power, and the battery module outputs the second power when the first electric potential of the first power is lower than the second electric potential of the second power.
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.
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.
