摘要： An improved winding structure of a transformer, wherein the transformer comprises a winding base externally set with an isolating plate, the transformer is divided into a primary side region and a secondary side region by the isolating plate. The primary side region has a winding reel for a pre-formed wire set to sleeve on while the secondary side region is divided into a plurality of winding grooves by a plurality of partitions for placing a wire in the grooves, and an iron core set is set on the outside of the winding base and the hollow structure, which altogether form an transformer. In the present invention, an pre-formed wire set is sleeved on a primary side winding reel, therefore, the costs of traditional hand-winding will be displaced, and the manufacturing quality and usage stability of transformers will be effectively improved as well.

摘要： The locked phase active power current control circuit is composed of a DC source, an electronic switch, a driving transformer, a phase detecting unit, a current intercepting unit and a square wave controller. A DC signal provided by the DC source is converted into a square wave signal by the electronic switch for the driving transformer to operate a load. The electronic switch outputs the square wave signal to the phase detecting unit whereat a phase signal of the square wave is detected and the detected signal is transmitted to the current intercepting unit whereat the detected signal is compared with the current intercepted at the electronic switch, the driving transformer, or the load, and the comparison result is fed back to the square wave controller so as to set the operation frequency of the electronic switch. The essential principle of the present invention is based on the fact that the square wave is in phase with the first harmonic wave.

摘要： A control device for multiple lamp currents of a liquid crystal display (LCD) backlight source, comprising an electronic power switch, a transformer, an inverter and an integrated circuit (IC) feedback control module. The transformer has a primary side connected to the electronic power switch and a secondary side having two ends each connected to an end of a set of lamp composed of two lamps. The inverter has three sets of coil connected to the other end of the two sets of lamp. The IC feedback control module is connected between the inverter and the electronic power switch and through which currents flown through the two sets of lamp may be balanced. Meanwhile, the current flown through the inverter is feedback to the IC feedback control module by which a control signal is outputted to the electronic power switch by determining and processing the feedback current, thereby controlling an output signal from the electronic power switch. Therefore, luminance of the multiple lamps in the LCD backlight source may be controlled and maintained.
