Power supply

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.

A transformer without coil racks includes a winding set, multiple conductive plates and an insulation mounting sheet. The winding set includes a coil portion and a magnetic core set running through the coil portion. The magnetic core set includes at least one inner magnetic core portion and at least two outer magnetic core portions that are spaced from each other by a gap. Each conductive plate includes a connecting section and two extended arms connected to two ends of the connecting section and running through the gap. The insulation mounting sheet includes multiple retaining slots corresponding to the gap to allow the extended arms to pass through and multiple retaining portions each being formed between two neighboring retaining slots to prevent the extended arms from contacting each other. The conductive plates run through the retaining slots and are confined by the retaining portions from moving.

The present invention discloses a multi-input power-switching circuit, which comprises: more than one power input terminal, more than one detection/evaluation circuit, and a switching/controlling unit. A switch is arranged in the path via which the input power is received by the power input terminal and then transferred to the power conversion unit. Each detection/evaluation circuit receives a partial voltage signal from one input power and generates a detection signal according to the partial voltage signal. The switching/controlling unit receives the detection signals from the detection/evaluation circuits, determines which power input terminal has a higher voltage level according to the detection signals, and generates a turn-on signal to turn on the switch connected with the power input terminal having a higher voltage level. Thereby, the power conversion unit can acquire a higher voltage input power and provide a stable driving power for a load.

An output adapting device of a plug-in power system is used to connect an output terminal of the plug-in power system with an input terminal of an electronic device, so as to transmit the power from the plug-in power system to the electronic device. The adapting device includes an output adapting terminal and an input adapting terminal respectively corresponding to the output terminal and the input terminal, in which corresponding pins of the corresponding terminals have identical potential, and at least one corresponding pair of pins of the output adapting terminal and the input adapting terminal have different potential. Furthermore, the adapting device also includes an adapting unit for adapting and outputting the power from the output adapting terminal to another pin with identical potential of the input adapting terminal. Therefore, the output terminal of the plug-in power system can be standardized for widely applying in various electronic devices.

A blade server equipped with hot plug function mainly includes a plurality of small servers which have respectively a logic processing main board and a power adapter card to be electrically connected to the logic processing main board in normal conditions. A power integration panel is provided that has a coupling port to be coupled with a power input port of the power adapter card in a hot plug fashion. Thus a general logic processing main board can be used on a blade server and equipped with hot plug function without the need of fabricating another logic processing main board of a special specification.

A power output error free apparatus includes a power supply having a circuit board inside and a power transmission port on the surface. The circuit board has a plurality of electric connection zones electrically connected to the power transmission port. The power transmission port is connected to a connection line which has a connection port on one end corresponding and connecting to the power transmission port and a coupling end on other end connecting to a computer main board. The coupling port has a ps-on (power-supply-on) signal pin to control activation of the power supply. The power transmission port has a dummy pin or HIGH potential on a location corresponding to the ps-on signal pin. As a mistaken connection occurs by switching the connection port with the coupling port, the ps-on signal cannot be transmitted through the dummy pin or HIGH potential of the power transmission port.

A backup-type power supply system aims to integrate power output according to different potentials through different power supply modules. Each power supply module includes backup-type N+1 power supply devices and an independent power balance unit to output power in a balanced fashion so that users can add the power supply module of independent potential according requirements. Thereby transformation power loss of the power supply devices can be reduced. The power supply devices can be designed with different specifications and dimensions corresponding to different electronic devices.

A power supplying system includes a switching control circuit connected to a stand-by power source so as to receive electrical power therefrom. The switching control circuit is further connected to a power-supplying unit and is activated to control operation of the power-supplying unit in a selected one of an ON state, where the power-supplying unit supplies electrical power for operating a heat-dissipating fan, and an OFF state, where the power-supplying unit ceases to supply the electrical power to the heat-dissipating fan. A delayed closing device receives a power-OFF signal from the power-supplying unit at an instant the power-supplying unit is operated from the ON state to the OFF state, and connects the heat-dissipating fan to the stand-by power source upon receiving the power-OFF signal to enable the heat-dissipating fan to receive electrical power from the stand-by power source and permit continued operation of the heat-dissipating fan even after the heat-dissipating fan ceases to receive the electrical power from the power-supplying unit.

A load balancer is to be used in a power supplying system which includes at least two power supplying units that are connected in parallel to supply power concurrently to operate an electrical load. The load balancer includes at least two sensors, each of which is adapted to generate an ac sensor output corresponding to power output of a respective one of the power supplying units. Each of at least two rectifying and filtering circuits rectifies and filters the ac sensor output of a respective one of the sensors so as to obtain a corresponding dc sensor output. A microprocessor receives the dc sensor outputs from the rectifying and filtering circuits, and calculates an average input value therefrom that corresponds to a balanced power output for the power supplying units. The microprocessor compares each of the dc sensor outputs with the average input value, and when one of the dc sensor outputs is larger than the average input value, indicating a condition in that the power output of one of the power supplying units is higher than the balanced power output, the microprocessor generates a load adjustment signal to control the power supplying unit with the higher power output so as to decrease its power output to the balanced power output.
