20090323382 | ADAPTER CONNECTION STRUCTURE - The present invention discloses an adapter connection structure, which comprises a first converter and a second converter. The first converter is connected to at least one input terminal to receive an input power and converts the input power into a transitional power. The second converter is connected to the first converter via a transit cable to transmit the transitional power, converts the transitional power into a DC output power and outputs the DC output power via a DC power cable. As the transitional power transmitted from the first converter to the second converter is in form of a high-voltage and high-frequency AC power or a high-voltage DC power, the power transmission loss in the transit cable is reduced. Therefore, the present invention not only can reduce transmission loss but also can adopt a less expensive cable. Thus is reduced the total cost of buying and using the adapter. | 12-31-2009 |
20110305056 | DESK TOP ITEM WITH LED MEANS HAS USB-UNIT(S) OR USB-MODULE TO CHARGE OTHER ELECTRIC OR DIGITAL DATA DEVICE(S) - The Desk Top items with LED means has USB-unit(s) or USB-Module to charge other electric or digital device(s) which offer people to charge smart phone or electric & digital data device from near by place items to quick charge other device(s) while people work, rest, stay. The said desk top items with LED means offer people including illumination, visual effects, smell, airflow, liquid, food, sound, music, digital data outputs and put items near by people stay or locations so add the said USB-unit(s) or USB-Module on the said Desk Top items with LED means will easily to allow people to get desired power source from USB-unit(s) or USB-Module's output end(s) to charge the items at most convenient near-by place than before. The said items may in group of combination selected from LED lamp, light fixture, air freshener, air fan, liquid device, food device, radio, music device, sound device, clock, weather station, electric photo frame, or any conventional available electric items with LED means. Same as desk top items with LED means has Outlet-unit(s) or Outlet-modules to supply the electric power to other electric or digital data device(s). | 12-15-2011 |
20120026771 | VEHICLE-USE POWER SUPPLY CONTROL APPARATUS AND CONTROL APPARATUS FOR CONTROLLING ELECTRIC ROTATING MACHINE MOUNTED ON VEHICLE AS MAIN ENGINE - The vehicle-use power supply control apparatus is for controlling transmission of electric power between a vehicle-mounted power supply apparatus including switching elements turned on and off in accordance with manipulation signals and an external power supply located outside the vehicle. The vehicle-use power supply control apparatus includes a control section to output an electric power transmission command signal depending on an electric power transmission request signal received from an external device, and a manipulation signal generating section to generate the manipulation signals based on the electric power transmission command signal received from the control section. The control section is configured to operate in order that noise sound generated due to switching operation of the vehicle-mounted power supply apparatus is within an audio frequency range. | 02-02-2012 |
20140286071 | POWER CONVERSION DEVICE HAVING BATTERY HEATING FUNCTION - A power conversion device having a battery heating function includes a battery, a converter, a temperature sensor, and a controller. The converter is coupled between the battery and a DC link. The temperature sensor measures a temperature of the battery. The controller controls the converter based on the temperature measured by the temperature sensor so that the battery repeats charging and discharging during the battery heating mode, thereby heating the battery. | 09-25-2014 |
