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 for a redundant power system includes a housing, a first circuit board, a second circuit board and a cooling fan. The first and second circuit boards are sequentially disposed in the housing. The length of the first circuit board is smaller than that of the second circuit board. Between the first and second circuit boards is a gap. The first and second circuit boards are each distributed with multiple electronic elements, and are connected by at least one electrical connecting line. The electronic elements form a power supply circuit, in which a bridge rectification module is disposed on the first circuit board and close to the gap. The cooling fan is at least connected to the first circuit board and a second circuit board to locate in the gap, and directly provides the bridge rectification module with a first cooling air current when activated.
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 start-up architecture of a redundant power supply system is provided. The redundant power supply system is electrically connected to a load, and includes N+M power supplies, where N≧1 and M≧1. The start-up architecture includes a power integration backboard electrically connected to the power supplies, and a mode switching member. The power integration backboard includes an activation circuit, and has a synchronous booting mode in which the power supplies are simultaneously activated and a sequential booting mode in which the power supplies are sequentially activated. The mode switching member is electrically connected to the activation circuit, and receives a manual switching of a user to output a synchronous booting signal that controls the power integration backboard to enter the synchronous booting mode and to output a sequential booting signal that controls the power integration backboard to enter the sequential booting mode.
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 thin keyboard command trigger structure includes a circuit board and a frame. The frame is stacked over the circuit board and formed an outer frame, a plurality of inner frames and a plurality of keycaps in an integrated manner. The outer frame has a plurality of holding zones. Each keycap is held in one of the holding zones. The outer frame and the keycap are bridged by one inner frame. Each inner frame has at least two first connecting portions connected to the outer frame and at least two second connecting portions connected to the keycap. Each first connecting portion and each second connecting portion are bridged by a support portion which has a bend spot and can generate deformation when the keycap is moved to the trigger portion. The support portion at the second connecting portion is at an elevation higher than the first connecting portion.

Abstract:
A support rack for a wireless electronic device is installed on a keyboard and integrally fabricated from a plastic sheet. The support rack includes a positioning segment, a bearing segment and a support segment. The positioning segment includes a holding zone to hold a wireless electronic device. The bearing segment is connected to one side of the positioning segment opposite to the keyboard and includes at least one retaining portion. The support segment includes a leaning section connected to the positioning segment via a first bend portion, and a holding section connected to the leaning section via a second bend portion to couple with the retaining portion. The first bend portion is formed at a thickness smaller than that of the leaning section and the positioning segment, and the second bend portion is formed at a thickness smaller than that of the leaning section and the bracket section.
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.
