The full bridge circuit is connected to a source DC voltage. The transformer is connected to full bridge circuit and receives the source DC. The transformer has a stationary winding and at least one selectable winding connected in series. If the source DC voltage is lower than a threshold value, the switch is turned on to increase the coupling ratio of the transformer. Therefore, the transformer converts the source DC to a DC voltage in a required voltage level.||12-26-2013|
|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|
|20130241291||UNINTERRUPTIBLE POWER SUPPLY SYSTEM HAVING A SIMPLIFIED VOLTAGE DETECTION CIRCUIT - A UPS system having a system ground terminal includes a main circuit having a power input terminal set connected to the AC mains, two switches respectively corresponding to a live line and a neutral line of the AC mains, a frequency detection module connected to the power input terminal set, a voltage division module composed of multiple voltage dividers, and the two switches and a central controller grounded through the system ground terminal and connected to the frequency detection module. The system ground terminal is connected to the neutral line through one of the switches. The central controller and the neutral line are equipotential after the frequency detection module detects a normal mains power and the central controller controls the switch connected to the neutral line to switch on. With the foregoing circuit, the UPS system can detect the voltage of the mains power in a simplified fashion.||09-19-2013|
|20130226363||SHUT-DOWN CONTROLLING SYSTEM FOR POWER DISTRIBUTION UNIT - A shut-down controlling system for power distribution unit (PDU) has a computer a PDU and multiple electric apparatus connected to the PDU. The PDU has multiple outlets and stores a shut-down controlling procedure and a shut-down period for each of the outlet. The PDU automatically communicates with the electric apparatus and obtains the actual shut-down period of the present electric apparatus. The PDU further determines whether the preset shut-down period is larger than the actual shut-down. If yes, the PDU cuts out the AC power source of the selected outlet when the preset shut-down period is achieved. If not, the PDU cancels the shut-down command and notifies the computer. Therefore, a manager will resets the shut-down period of the selected outlet to ensure that each electric apparatus has enough time to complete the shut-down procedure.||08-29-2013|
|20130154545||UNINTERRUPTIBLE POWER SUPPLY HAVING EFFICIENT POWER CONVERSION - An uninterruptible power supply having efficiency power conversion has an AC to DC power conversion circuit, a battery power conversion circuit and a control circuit. The AC to DC power conversion circuit is parallelly connected to the battery power conversion circuit to convert the AC power of an AC mains into a DC power and supply the DC power to a load. When the AC mains stably supplies power, the control circuit controls to activate the AC to DC power conversion circuit and supply power to the load through the AC to DC power conversion circuit only. As there is only one power conversion between the AC mains and the load, the power conversion efficiency can be enhanced.||06-20-2013|
|20130132879||OPERATING PANEL FOR AN UNINTERRUPTIBLE POWER SYSTEM AND OPERATING METHOD THEREOF - An operating panel of an uninterruptible power system (UPS) has multiple function buttons, a control module and an LCD display. Each of the function buttons is controlled to enter a main function when it has been pressed more than a threshold time or to perform a first action when it has been pressed less than the threshold time. The control module is connected to the multiple function buttons to determine whether any of the function buttons has been pressed more than the threshold time. The LCD display is connected to the control module to show operating information. A user of the UPS can directly choose a main function by long pressing the corresponding function button, and then further select to a particular sub-function by shortly clicking the function buttons.||05-23-2013|

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|
|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|
