摘要： A backup power device (3) which can be installed inside an industrial-standard microcomputer (1) in unused space designed for a disc or hard disc drive, by taking advantage of the attachment possibilities (4) meant for the disc or hard disc drive. The alarm lights and operating switches (9) of the backup power device are visible to the user on the front panel of the computer (1). The backup power device (3) is connected inside the computer parallel to the computer's power source. When the computer's power source stops working due to a power failure, the backup power device (3) immediately begins to supply electricity to the computer from a battery or corresponding energy store.

摘要： A power control circuit for a device such as personal computer, including a laptop or notebook computer, which can conserve battery use, prevent power surges to promote longer battery charges and longer battery life, and can assure that circuitry is correctly biased. The power control circuitry of the present invention achieves these objectives by appropriately staggering the powering on of circuit components of the computer. A circuit for achieving these objectives may feature at least one memory (20, 22, 24) for storing power control state data and a multiplexer (15) for receiving the power control state data stored in the at least one memory (20, 22, 24). Further, a plurality of serially connected power control output circuits (21-30) connected to the multiplexer (15) output power control signals based on the power control state data stored in the at least one memory (20, 22, 24). A first of the plurality of serially connected power control output circuits (21-30) has a minimum delay and each succeeding of the plurality of serially connected power control output circuits (21-30) has an increasing delay.

摘要： This invention relates to a power system which connects/disconnects battery (12) from a load (10) such as a computer system, and includes a first circuit arrangement (15) which sets a first reference voltage level at which the energy source is connected through an FET device to the computer system, a second circuit arrangement (15) that sets a second voltage level at which the energy source is disconnected by the FET device from the computer system and a third circuit arrangement (15) which controls the FET device so that said FET device is forced into either its ON or OFF state once one of the reference voltages is reached. A circuit (30) reduces power dissipation in a battery charge circuit (28) by forcing the input voltage to track the battery voltage as the battery charges/discharges.

摘要： In a computer system, when an expansion unit is connected to a computer main body (1) by an interface card (3), power supply control and I/O port selection are performed at the start of the computer system. In the power supply control, when an expansion power supply of the expansion unit is turned on, a first voltage is supplied to a main power supply (20) of the computer main body (1). When the main power supply (20) is turned on, main voltages are supplied to computer main body elements from the main power supply (20) in response to the main voltage, and a second voltage is supplied to the expansion power supply through the interface (3). In response to the second voltage, expansion voltages is supplied to expansion unit elements, and an interface voltage is supplied to the interface (3). After the power supply control is completed, the I/O port selection is performed. The port addresses of the I/O ports in the computer main body (1) are compared with the port addresses of the I/O ports in the expansion unit. If both port addresses coincide with each other, the I/O ports in the computer main body (1) are disabled, and the I/O ports in the expansion unit are enabled.

摘要： Un système d'alimentation en tension à plusieurs sorties de tension (10, 36) est alimenté par au moins deux sources de tension (12, 14). Une sortie de tension (10) peut être alimentée en alternance par une première source de tension (12) ou par une autre source de tension (14), au moins une autre sortie de tension (36) étant en permanence alimentée par l'une de ces sources de tension. L'alimentation en alternance de la sortie de tension (10) s'effectue au moyen de signaux de commande (S1, S2) qui commandent l'état de commutation d'agencements commutateurs (T1, T2, T3) tout en allongeant les temps de commutation. Ce faisant, des processus de commutation en sens inverse se chevauchent. Par suite de ces dispositions, la perte de puissance au niveau des agencements commutateurs (T1, T2, T3) est réduite, et des niveaux de tension largement compatibles sont produits au niveau des sorties de tension (10, 36).

摘要： Bei einer Stabilisierungsschaltung für die Versorgungsspannung eines Ein-Chip-Mikrocomputers können beim Einschalten der Versorgungsspannung am Mikrocomputer undefinierte Zustände eintreten. Es wird deshalb eine Stabilisierungsschaltung vorgeschlagen, die die Versorgungsspannung erst auf dem Mikrocomputer durchschaltet, wenn diese in einem zulässigen Arbeitsbereich liegt. Auch das Abschalten der Versorgungsspannung vom Mikrocomputer erfolgt definiert.

摘要： According to one embodiment, a power circuit includes a DC-DC converter and an activation control circuit. The DC-DC converter converts input voltage into voltage that is different from the input voltage. The activation control circuit sends a first enable signal to start operation of the DC-DC converter when voltage depending on the input voltage becomes equal to or higher than a first threshold voltage, and sends a second enable signal to start operation of a load connected to an output side of the DC-DC converter when the voltage depending on the input voltage becomes equal to or higher than a second threshold voltage. The second threshold is higher than the first threshold voltage.

摘要： An example system includes a first data port and a second data port. The system includes a controller electrically coupled to the first and second data ports. The controller is to cause the first data port to receive power. The controller is to cause the second data port to output at least a portion of the received power. The controller is to detect an impending loss of power to the first data port. The controller is to cause the second data port to transmit an urgent power request.
