New description: [New technical field] The present invention relates to a transformer, in particular to a transformer capable of detecting an output state and a circuit thereof. [Prior Art] ^The backlight of the liquid crystal display usually adopts the discharge tube circuit, and the circuit design - 4 _ & will consider (4) the state of the discharge tube, by analyzing the price nickname to perform the operation of the circuit at the '5' Turn off the power supply or power, reduce the voltage, and so on. - For example, the protection circuit for discharge tubes disclosed in No. 9412g(10) and 帛9(2) of No. 9 Diode 92921581 in the Republic of China patents is directly connected to the discharge s circuit. Although it has the effect of detecting the state of the discharge tube, When connected to the discharge tube circuit, the circuit layout makes the circuit layout difficult due to the high Creepage distance. In addition, as shown in the Patent Application No. 92212167 of the Republic of China, the protection circuit for the tube is characterized in that it is transmitted through the f-type detection of the "light source" of the sensing discharge tube, instead of being directly connected to the discharge tube, thereby observing that it is necessary to adopt: An electric component (such as a photodiode) is used as a detecting medium. However, when the number of f tubes is increased, the number of optoelectronic components used is also increased, so that there is an increase in cost on a large-sized liquid crystal display. Disadvantages, in addition, the use of the light source as a speculation to determine the state of each discharge tube. [New content], for the purpose of this new model, is to provide a circuit layout easy and low cost of the detectable output state of the transformer and its circuit . 3 M366746 Thus, the transformer of the novel detectable output state comprises a first winding area, a second winding area, a primary coil, a secondary coil, an induction coil, and a core unit. The second winding area is spaced apart from the first winding area. The primary coil is wound around the first winding zone. The secondary coils are wound around the second winding zone at intervals. The induction coil includes a start end, an end end, and a winding segment formed between the start end and the end end, the start end and the end end being _ extending to the first winding area, the winding section It is wound between the secondary coils. The core unit is formed with a magnetic path connected to the primary coil, the secondary coils, and the induction coil. The transformer circuit for detecting the output state of the present invention applies the above-mentioned transformer, and further comprises a switching unit, a feedback unit, and a power control QP 7G early. The switching unit is electrically connected to the primary coil. The feedback unit is electrically connected to the induction coil. The power control unit is configured to control power output to the switch unit, the switch circuit, the feedback unit, the power control unit, and the first winding area are all located at a distance from the second winding area -side. The utility model has the beneficial effects that when the transformer is operated, the induction coil can generate a sensation of entanglement with the secondary coils, so that the change of the signal on the responsive coil can determine the secondary coils. Whether the working state is normal' without the need for additional detecting components, and achieving the advantage of low cost, M366746 In addition, since the starting end and the ending end of the induction coil are extended to the winding area, only the layout is required when designing the circuit layout. The first:wrap: area can be electrically connected to the start end and the end end without the advantage of being easy.
