Abstract:
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.
Abstract:
A loadable composite backup power system can be configured and assembled to become a small backup power system or a large backup power system according to actual requirements. In the condition of a smaller loading requirement, one power unit consisting of M+P sets of power supply devices (base and backup power supply) can be selected to connect electrically to a main power distribution unit to form the small backup power system. When the load increases, an extra power unit consisting of M+P sets of power supply devices can be added and connected to the main power distribution unit to form the large backup power system that integrates all the base and backup power supply. Hence the power expansion flexibility of the existing backup power system can be enhanced.
Abstract:
A power output fool-proof 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 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.
Abstract:
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.

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.

Abstract:
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.
