Description of the invention (4) Fixed fan. To assemble this inverter, first prepare a secondary winding medium 71 on the reel 12, and the lead wire is the reel 10 connected to the terminal 41, and the winding wire 72 is rolled once on the roll sleeve 22. The reel 20 quickly connected to the terminal 4δ, and the secondary reel 73 is wound on the reel 32, and the lead is connected to the reel 30 of the reel 46. However, insert the outer leg 5U3 into the two holes of the roll 12 and 32, insert the central leg into the hole of the roll_22, and load the roll 10, 20, 30 on the heart 50, and then bond the heart 60 50 limping in the heart. As a result, it is possible to form a two-output type reverse transformer having terminals 45 and 47 for external connection on opposite sides, and a terminal 45 on the other side. In addition, as in the above-mentioned inverter transformer, as shown in FIG. 3, the upper part of the core 50 is formed. The protrusion 54 protruding toward the core 60 between the primary winding medium 72 and the secondary winding line 71, and the primary winding 60 The protrusion 55 protruding from the centripet 60 of the winding line 72 and the secondary winding line 73 can form a two-output reverse transformer® that weakens the electromagnetic coupling between the primary winding line 72 and the secondary winding lines 71 and 73. By adding the second reel and the third reel by adding the second reel to the two sides of the reel converter's 20 sides (the opposite side after 45 孅 is installed) in the second lap, a 3 output can be formed. Type reverse regulator. In this case, at the same time, the cores 50 and 60 should be enlarged, and the cores 50 should be added to the outer leg of the fourth reel, and the three secondary windings M should be electromagnetically coupled to the primary winding 72 with the same degree of coupling. The above-mentioned converter is its secondary winding 71, primary winding 72, and secondary winding 73, which are wound around the reels 12, 22, 32 extending in the up and down direction.

Description of the invention (f) It is a transformer in which the directions of the center sleeves of the coils are parallel to each other. However, as shown in FIG. 4 of the present invention, the primary winding 72 and the secondary winding 71, 73 are wound on one roll 80, and the transformers with the central axes of the windings 71, 7, 73 on the same straight line are also The same applies. The reel 80 has three coil canals 81, 82, 83 separated by a brim 85. However, the primary winding 72 is wound in the central winding groove 82, and the secondary windings 81 and 83 on the outside are wound with the secondary winding 71 and the secondary winding 73, respectively. In addition, the secondary windings 71 and 73 on the high-voltage side will not break the insulation (the 刖 M cap 臁 86 is divided into multiples and wound. A pair of hearts 90 and 95 with an E-shaped cross-section is inserted into each center leg In the hole 88 penetrated by 91, 96, M forms a closed magnetic circuit. The fifth garden is an example of a converter circuit that uses the 2 output type reverse transformer T of the present invention to ignite two light bulbs 1,2 峙 at the same time. The foregoing description of the transformer is omitted. For example, the winding is wound around the reel 22 of the reel 20 and the secondary winding wire 72, and its lead wire is connected to the feedback winding wire of the terminal 45. Q1, Q2 are KK push-pull type connected switches The electric crystal is miscellaneous, R is a side-channel resistance, Cc is a resonance capacitor connected in parallel to the primary winding 72, and the middle tap of the primary winding 72 is quickly connected to an input source (not shown) via choke 圔 L. One end is grounded One end of the secondary winding 71 is connected to the bulb 1 through a ballast container, and the other end of the bulb 1 is grounded. The other end of the secondary winding 73 that is grounded at one end is connected through a mold container C2 for flow. To bulb 2, the other end of bulb 2 is grounded. In addition, use 3 Figure Na Yang weakens the electromagnetic coupling between the primary winding 72 and the secondary winding 71, 73.

Description of the invention (>) is 0 Although the converter circuit in Figure 5 uses the transformer as 2 outputs, and it is intended to light two bulbs, this transformer can be ignited As shown in Figure 6, it can also be used as a 1-output type with doubled voltage. The two ends of the secondary winding 71 and the secondary winding 73 of the transformer T are connected to the two ends of the light bulb 3 through the capacitors C1 and C2 respectively, and the double voltage of K makes one light bulb. Lighter. The primary side of the transformer T has the same configuration as the circuit of FIG. 5. In the case of this single output type, the transformer T can be configured as shown in Fig. 3, and C1 and C2 of the ballast capacitors can be omitted. [Effects of the Invention] According to the present inventor, since only one lamp can be ignited two lamps at the same time, the installation area and cost can be reduced compared with the known examples in which a rain transformer is required. Except for this, the driving frequency of each bulb will become the same, so no jumping noise or flicker will occur. Furthermore, when a large LCD monitor is installed with one incline above and below the liquid crystal panel, the transformer of the present invention having secondary windings at both ends has the advantage of being easy to lay out. Furthermore, in addition to being able to be made without a ballast capacitor, it can be made thin, and has the effect of being used as a voltage-doubling output transformer.
