| 20100060400 | Transformer and spiral flat winding thereof - A transformer includes a bobbin, an iron core and two spiral flat windings. The bobbin has a primary side portion, a secondary side portion and a separating plate. The separating plate is provided between the primary side portion and the secondary side portion. The first, second and third through holes are in communication with each other. The iron core penetrates the first, second and third through holes. The spiral flat winding is formed from a plurality of flat loops. The two spiral flat windings are provided on both sides of the separating plate and surround the primary side portion and the secondary side portion. Via the above arrangement, the spiral flat winding can be disposed around the bobbin, so that the assembling process can be performed simply and quickly. Thus, the working hours for assembling and the cost can be reduced. | 03-11-2010 |
| 20110090649 | TILT-TYPE HEAT-DISSIPATING MODULE FOR INCREASING HEAT-DISSIPATING EFFICIENCY AND DECREASING LENGTH OF SOLDER PIN - A tilt-type heat-dissipating module for increasing heat-dissipating efficiency and decreasing length of solder pin is disposed on a circuit substrate. The tilt-type heat-dissipating module includes a substrate unit, a heat-dissipating unit and an electronic unit. The substrate unit has a heat-dissipating body disposed on the circuit substrate, and one part of a top surface of the heat-dissipating body is a first inclined plane. The heat-dissipating unit has a plurality of heat-dissipating fins connected to the heat-dissipating body. The electronic unit has a plurality of electronic elements disposed on the first inclined plane of the heat-dissipating body. Each electronic element has a plurality of pins bent downwards from a bottom thereof in order to electrically connect to the circuit substrate, and heat generated by the electronic elements is transmitted to external environment by matching the heat-dissipating body and the heat-dissipating fins. | 04-21-2011 |
| 20110115305 | ELECTRICAL POWER-SAVING CONTROL APPARATUS, POWER SUPPLY INCLUDING THAT APPARATUS AND POWER-SAVING METHOD THEREOF - A power-saving control apparatus for reducing power consumption of a power supply is provided. The present invention includes a switching circuit and a rectifier circuit. The rectifier circuit rectifies an AC signal to a DC signal. The switching circuit controls either the AC signal or the DC signal as an input signal to an EMI filter of the power supply. Therefore, when the EMI filter receives the DC signal, the present invention achieves the effect of power-saving of the power supply. | 05-19-2011 |
| 20110116203 | APPARATUS AND METHOD FOR DRAINING STORED POWER - Apparatus and method for draining stored power are disclosed, which the apparatus and method are applied to an EMI filter circuit for draining power. When the power supply circuit is not working, the apparatus provides a bleeder resistor to drain the power stored in the capacitors of the EMI filter circuit. On the other hand, when the power supply circuit is working, the apparatus provides an open-circuit resistor which has extremely large electrical resistance in order to stop draining power. Thus, the apparatus for draining stored power will not cause extra power waste. | 05-19-2011 |
| 20110241638 | FEEDBACK VOLTAGE STABILIZING APPARATUS, METHOD, AND POWER CONVERSION SYSTEM - Feedback voltage stabilizing apparatus, method, and power conversion system are disclosed. The apparatus includes a first switching unit, a second switching unit, and a conduction control unit. In which, the first switching unit is coupled to a feedback circuit for controlling whether a feedback signal is transmitted from a first end to a second end. The second switching unit is for avoiding voltage vibrations which caused by the feedback signal occurring at the second end. By capturing a detection signal, the conduction control unit can determine whether to simultaneously turn on the first switching unit and the second switching unit, in order to eliminate the voltage vibrations, or not. | 10-06-2011 |
| 20110248694 | SOFT SWITCHING APPARATUS, METHOD, AND POWER CONVERSION SYSTEM - Soft switching apparatus, method, and power conversion system are disclosed. The apparatus includes a main switching unit and a buffer unit for adjusting a voltage level of a switching signal, in order to change an internal resistance of the main switching unit and to reduce the sudden change to a voltage and a current flowing through the main switching unit. | 10-13-2011 |
| 20110254648 | MOVABLE TRANSFORMER EMBEDDED INTO AN OPENING OF A PCB AND A METHOD OF INSTALLING THE SAME - A movable transformer embedded into an opening of a PCB includes a first bobbin unit, a second bobbin unit, a third bobbin unit, a winding unit and a magnetic unit. The second bobbin unit is electrically connected to the PCB. The third bobbin unit is electrically connected to the PCB. The winding unit is disposed around the first bobbin unit, the second bobbin unit and the third bobbin unit. The magnetic unit passes through the first bobbin unit and disposed outside the first bobbin unit. In addition, one side of the first bobbin unit is slidably mated with the second bobbin unit, another side of the first bobbin unit is slidably mated with the third bobbin unit, so that the first bobbin unit is selectively moved from one position above the opening to another position in the opening. | 10-20-2011 |
| 20110255308 | SYSTEM, MODULE, AND METHOD FOR CONSTANT CURRENT CONTROLLING OF POWER CONVERTER - A system, a module, and a method for constant current controlling of a power converter are disclosed. The constant current controlling system includes a power converter and a constant current controlling module. The power converter has a transformer and a switching unit. The switch unit is coupled with the primary coil of the transformer. The constant current controlling module is coupled with the transformer and the switching unit, for generating a discharge time and detecting a current waveform signal, before generating a control signal in order to adjust the duration of the switching period of the switching unit to ensure that an output current of the power converter may remain substantially the same. | 10-20-2011 |
