Abstract: A transformer includes a main body and a secondary winding. The main body has a primary winding partition, several secondary winding partitions and two end portions. Several leads are disposed in either end portion. A wire-guiding area is formed in a sunken area in the primary winding partition and a buffer region is formed between the primary end portion and the primary winding partition. The secondary winding is wound around the core on the secondary winding partitions. One end of the wire runs from the secondary winding partitions to the wire-guiding area. Before the secondary wire goes into the buffer region, the secondary wire is folded for several times and then is twisted and rolled for several turns to make the secondary wire thicker. Then the secondary wire goes into the buffer region and then is connected to one of the primary leads. Due to the wire-guiding area and buffer region, the secondary wire would not be affected or pressed against by the primary wire.

Abstract: 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.

Abstract: An improved winding base structure of a transformer is assembled by combining a primary-side winding base and a secondary-side winding base. The selection of the material of the primary-side winding base and the secondary-side winding base is dependant on the compression-resistant capability because the primary-side input and the secondary-side output of the transformer bear different voltages. The outside of the assembled winding base is disposed with grooves in which the wires are wound, and the center of the winding base is disposed with a through hole for an iron core to be put therein to form a transformer. The sectional winding base of the subject application is characterized in that the primary-side winding base is made of lower compression-resistant material and the secondary-side winding base is made of higher compression-resistant material. Therefore the production cost of the winding base is reduced.
