20090179496 | Power saving uninterruptible power supply - The power saving uninterruptible power supply (UPS) has a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. The transformer has a primary side and a secondary side. The primary side is coupled to an alternating current (AC) power source. An AC input terminal of the AVR is coupled to the secondary side of the transformer to acquire an inducted AC power source to regulate the inducted AC power source to output to a load. The charger-and-inverter is coupled to the secondary side of the transformer to acquire a recharged power source to convert to a recharged current. The normal mode determination unit is coupled to the AC power source and the battery to detect a power supply status of the AC power source and battery capacity, so as to further determine whether current operation is normal. | 07-16-2009 |
20090289504 | Power saving uninterruptible power supply - The power saving uninterruptible power supply (UPS) has a first and second switches, an energy spared switch, a transformer, an automatic voltage regulator (AVR), a charger-and-inverter, a normal mode determination unit and an electric switch. When the utility power is stable, the first and second switches are connected together to supply the utility power to a load. At the time, the energy spared switch is physically disconnected with the utility power and the transformer and the AVR. Therefore, the transformer and AVR do not consume more energy of the utility power and the transforming efficiency of the UPS is increased. | 11-26-2009 |
20110095611 | Uninterruptible power supply supporting active loads - An uninterruptible power supply supporting active loads includes a charge and discharge module having a battery set and a charger charging the battery set with an input power, a switch circuit having at least two active switches connected to the battery set, a dynamic PWM control module connected with each of the active switches of the switch circuit, alternately outputting duty cycles composed of low-frequency square wave and high-frequency square wave and alternately controlling each of the active switches to turn on or off, and a transformer having a primary side connected with the switch circuit and a secondary side whose two terminals are connected with an output capacitor generating a filtering function in collaboration with an leakage inductor in the secondary side of the transformer. The uninterruptible power supply generates a quasi-continuous output satisfying the hold-up time demanded by an active load. | 04-28-2011 |
20120246492 | REMOTE POWER GROUP DISTRIBUTION CONTROL SYSTEM AND METHOD THEREFOR - A remote power group distribution control system has a host computer, at least one network server and multiple power distribution units (PDUs) connected to the host computer through the at least one network server. The host computer has a power distribution control module. Each PDU is connected with multiple power consuming equipment having identical or similar characteristics to supply an operating power and an uninterruptible power. When the power distribution control module is executed, the host computer searches the PDUs connected thereto through the at least one network server, displays all power-consuming equipment connected to each PDU, generates a group management window to assign each power-consuming equipment to a group, and remotely controls the power consuming equipment on a group basis. Accordingly, the present invention addresses a solution conveniently powering on or off remote power-consuming equipment pertaining to a group. | 09-27-2012 |
20120317428 | METHOD OF REMOTELY CONTROLLING POWER DISTRIBUTION UNITS - A method of remotely controlling power distribution units enables the power distribution units to automatically transmit messages to a server once connected to the server via a network. When a user logs into a server and requests to remotely control the associated power distribution units, the user only needs to enter the serial numbers or identification data thereof. The server then automatically searches for all power distribution units owned by the user, and provides a group management interface. The user can then group the power distribution units according to their locations or their properties in order to control the on and off thereof. Without knowing the IP addresses of the power distribution units, the user can readily control the power distribution units at different locations remotely. | 12-13-2012 |
20130046410 | METHOD FOR CREATING VIRTUAL ENVIRONMENTAL SENSOR ON A POWER DISTRIBUTION UNIT - A method for creating virtual environmental sensor on a power distribution unit is executed by a power distribution unit and has steps of connecting to a network and at least one power-consuming device, searching all environmental sensors through the network, receiving environmental condition messages sent from each environmental sensor, presenting at least one environmental condition range to determine if the environmental condition messages sent from each environmental sensor are out of one of the at least one environmental condition range, and powering on or off a corresponding power-consuming device when each environmental condition message is out of a corresponding environmental condition range. Using the method can create remote environmental sensors networked with the PDU and solve the expansion restriction, spatial limitation and intractable wiring arising from the environmental sensor embedded in the conventional PDU in the form of hardware. | 02-21-2013 |
20130119766 | METHOD FOR CONTROLLING UNINTERRUPTIBLE AND PARALLEL POWER MODULES - A method for controlling uninterruptible and parallel power modules has steps of parallelly and unloadably connecting multiple power modules to a load, acquiring a number and a load wattage of the power modules connected to the load and an instant load ratio, calculating a simulated load ratio in accordance with a simulated number of the power modules and the load wattage, if the simulated load ratio is closer to a half load and the redundancy requirement is met, unloading at least one of the power modules connected to the load so that other power modules connected to the load can share the additional load released from the unloaded power modules and the load ratio and output efficiency of each power module connected to the load can be enhanced. | 05-16-2013 |
20130246814 | UNINTERRUPTIBLE POWER SUPPLY AND METHOD FOR CONTROLLING POWER DISTRIBUTION UNIT BY THE SAME - A method for controlling power distribution unit (PDU) by an uninterruptible power supply (UPS) has steps of allowing logging in the UPS through a network, providing a web-based user interface and allowing adding an identification of at least one PDU to use sockets on the added PDU to simulate additional sockets on the UPS, performing a handshaking task with the added PDU, receiving information from the added PDU during performing of the handshaking task, displaying the received information of the added PDU on the web-based user interface and allowing either operating the UPS or controlling the added PDU. The method allows the UPS to be capable of communicating with all connected PDUs so the user can merely login the UPS to control and manage all PDUs connected to the UPS. | 09-19-2013 |
20130246816 | POWER DISTRIBUTION UNIT AND METHOD USING A SINGLE INTERNET PROTOCOL ADDRESS TO CONTROL MULTIPLE POWER DISTRIBUTION UNITS - A power distribution unit (PDU) performs a method using a single IP address to control multiple PDUs and has a controller and at least one network port connected to the controller. The controller provides an html-based user interface for users to set up virtual outlets therethrough. When multiple foregoing PDUs are connected through a network, one of the PDUs can be logged in with an internet protocol (IP) address, and the outlets of other PDUs are virtualized as added outlets of the login PDU. Outlet information associated with the original and added outlets of the login PDU can be simultaneously displayed on the user interface of the login PDU. Accordingly, users can employ a single IP address to control the outlets of all the PDUs. | 09-19-2013 |
