| 20110187333 | ENERGY-SAVING POWER CONVERTING APPARATUS CAPABLE OF BEING WAKED UP AUTOMATICALLY AND HAVING SUSPEND MODE - The present invention relates to an energy-saving power converting apparatus. The apparatus includes a power converter for providing electric power to an electricity consuming device and a state indicator adapted for being connected to a standard interface of the electricity consuming device. The state indicator is configured to be activated upon receiving power from the power terminal of the standard interface of the electricity consuming device when the electricity consuming device is in the working mode, while the state indicator cannot receive power from the power terminal when the electricity consuming device is in the non-working mode. The power converting apparatus further includes a receiving and controlling unit for placing a control switch in an electrically connected state to activate the voltage-transforming unit when the electricity consuming device is in the working mode. | 08-04-2011 |
| 20110157925 | ENERGY-SAVING POWER CONVERTER HAVING SUSPEND MODE - The present invention relates to an energy-saving power converter having a suspend mode. The power converter includes an output port for being electrically connected to the electricity consuming device; a voltage-transforming unit for outputting an output voltage appropriate to the needs of the electricity consuming device; a sensor for assessing the electricity consuming mode of the electricity consuming device, and a switch for selectively determining whether the sensor is to be powered. A wake-up unit is further provided to generate a wake-up signal for activating the voltage-transforming unit to provide power normally. The invention therefore solves the problem of unnecessary energy consumption resulted from a constant voltage conversion during the course when the electricity consuming device need not be supplied with power. | 06-30-2011 |
| 20100163390 | SWITCH EQUIPPED WITH DRIVING DEVICE FOR ESTABLISHING ELECTRICAL CONNECTION AND ADAPTED TO POWER SUPPLYING APPARATUS AND POWER SUPPLYING APPARATUS PROVIDED WITH THE SAME - The present invention provides a switch that is equipped with a driving device for establishing electrical connection and adapted to a power supplying apparatus, and a power supplying apparatus provided with the same. The power supplying apparatus has a main body, an output port, a voltage-selecting circuit and a switch for commanding the voltage selecting circuit to select the output voltage that is to be output via the output port. The switch has a plurality of resilient conductive terminals and at least one driving device. The insertion of a driving device will selectively establish electrical connection among some of the resilient conductive terminals, enabling the switch to form a circuit for adjusting the output voltage of the power supplying apparatus. | 07-01-2010 |
| 20100072965 | OUTPUT VOLTAGE FEEDBACK DEVICE FOR BEING USED IN A POWER SUPPLYING APPARATUS AND POWER SUPPLYING APPARATUS PROVIDED WITH THE SAME - The present invention relates to an output voltage feedback device for being used in a power supplying apparatus and a power supplying apparatus provided with the same. The power supplying apparatus provides electrical power via a wire set which includes a high level wire and a low level wire. The output voltage feedback device is provided with a voltage sensor and feedback unit for determining the voltage difference between the high level wire and the low level wire and the resultant measurement is transmitted back to the converter main body via the wire set in the form of a distinct electrical signal. The output voltage feedback device according to the invention can accurately determine the output voltage from the power supplying apparatus and, in case of occurring an output fault, interrupt the supply of power or enable an automatic compensation to reduce damage. | 03-25-2010 |
| 20090268355 | SAFETY OUTPUT DEVICE FOR USE IN A POWER CONVERTER AND POWER CONVERTER PROVIDED WITH THE SAME - The present invention relates to a safety output device for use in a power converter that includes a converter main body adapted for outputting a direct-current electric power at a predetermined voltage. The safety output device is adapted for being associated with an electricity consuming device that is powered by the power converter and comprises a wire set adapted for being electrically connected to the converter main body, a sensing controller for measuring a voltage difference in the wire set, and a switch adapted for being actuated by the sensing controller to permit electric conduction from the converter main body to the electricity consuming device when the voltage difference is detected to be substantially equal to the predetermined voltage. | 10-29-2009 |
| 20090212757 | Voltage transformer with sequentially switchable voltage selection circuit - A voltage transformer with a sequentially switchable voltage selection circuit is provided for converting input electrical energy through the sequentially switchable voltage selection circuit, which is arranged within the transformer body with its two ends electrically connected to an input port and an output port respectively, into one of a plurality of output voltage values and outputting the electrical energy. When it is desired to regulate an output voltage, a connection device must be plugged in a socket portion on the transformer body to initialize a micro control unit through feedback to change a voltage value sent to a voltage transformation unit, and in turn change the voltage of output electrical energy until a display device displays an ideal output voltage value. Then, the user removes the connection device, and the voltage value of the input electrical energy is converted into corresponding to the selected predetermined voltage value to output the electrical energy. | 08-27-2009 |
