New description: [New technical field] The author is related to a kind of piezoelectric transformer, especially the type _ part of the substrate is not polarized and retains the characteristics of the ceramic material 'as the secondary side, Insulated piezoelectric transformer with secondary side insulation. [Prior Art] Isolation transformer - generally refers to the general name of the transformer for preventing noise. Before entering various electrical products, Wei will threaten the power transformer, but the high frequency noise can still be extracted by the transformer and the second side. The capacitive effect, tree complexing or spoke mode of the line is entered into the line of the electrical product. However, because the power supply will inevitably be subject to the need to pass through the parts and then the gods, if you want to provide a big god system, _ change (four) itself is very huge, the workload isolation transformer is hundreds of kilograms, this is the reason. In recent years, due to the development trend of light, thin, short and small information products, it has become an important trend in the driving of liquid crystal display n-backlit cathode lamps: a note on the computer. Piezoelectric Wei secret micro-piezoelectric material machine view and Wei between the = conversion characteristics, in the piezoelectric element of the input Wengzhi _ feed near the threat ==== r electrical component resonance, complex _ electrical effect = stress The deformation mechanical energy is converted into electrical energy, which is converted by the piezoelectric element (4) to achieve (four). Piezoelectric variable turtle with high bribery (>4Q w/ : conversion efficiency (97%), high transformation ratio, high reliability, low height, small volume, weight change = margin, non-flammable, low price, no Winding and magnetic core, single structure, suitable for electromagnetic interference, and many other advantages. Automatic production of I can be insulated, = high output and effective reduction of pyrolysis temperature, _, _ is a lion compound The structure, the insulation layer and other layers are of different materials, the power loss is high, and when the high-strength is made, the composite material will not be able to be used. The fault is broken and damaged, and the M352136 cannot be Μ 'Unable to reach - the secondary side and the secondary side are insulated. The safety requirements, because of this, can not be used as an insulating piezoelectric transformer [new content] » ί above the problem 'The main purpose of this creation is in the green supply - an insulating piezoelectric transformer to substantially solve the prior art The absence of it effectively achieves the purpose of insulating the primary side and the secondary side, and can be used as an insulating piezoelectric transformer. Therefore, the insulating piezoelectric transformer disclosed in the present invention (for the above purpose) includes a substrate. Upper electrode, first-lower a pole, a second upper electrode and a second lower electrode, wherein the substrate is made of a ceramic material and has an upper surface and a lower surface, and the first upper electrode and the second upper electrode are disposed on the upper surface of the substrate and are not connected to each other The first lower electrode and the second lower electrode are disposed on the lower surface of the substrate and are not connected to each other. Meanwhile, the first upper electrode and the first lower electrode are symmetric with each other, and the second upper electrode and the first lower electrode are symmetric with each other. Composition _: underside and secondary side, by means of -trapping, secondary side respectively through DC high voltage to polarize the middle substrate which is cooled by the two sides of the electrode, while the unpolarized part remains in the middle The characteristics of the material, @ this, t input can be used as the secondary pressure and double 槪 edge when there is no fresh voltage. Because it is a single-layer design, you don't have to worry about it. As with the material of the job, there is a risk of breakage under high pressure. At the same time, by maintaining the physical properties of the material, when the DC voltage is input, the true insulation of the high-resistance state can be achieved. The purpose and characteristics of this creation and the understanding of Wei Youjin, the brain The detailed description of the drawing is as follows: - [Embodiment] As shown in Fig. 1A, a schematic diagram of an insulating piezoelectric transformer provided in the embodiment of the present invention. ^ Insulating piezoelectric transformer including a substrate 1 An upper electrode 21, a first lower electrode 22, a second upper electrode 31, and a second lower electrode 32. Meanwhile, please refer to FIG. 1B for an upper view of the insulating piezoelectric transformer provided by the embodiment of the present invention; The substrate 1 is substantially disk-shaped, that is, is circular in appearance from the top view, and can be formed by sintering of a ceramic material, and has a corresponding upper surface 11 and lower surface 12, first on The electrode μ is formed on the substrate 1〇6 M352136 depending on the polarization process and the physical properties of the material. Therefore, when a square wave is input from the primary side, a sine wave is output from the secondary side, which is generally operated by its resonance. The highest power output is obtained at the frequency. Through the experimental analysis, the author knows that the central unpolarized region 13 retaining the characteristics of the Tauman material has an impedance age that increases with the input frequency = and increases with the resonance frequency _ wide _. Therefore, when the input voltage is no frequency (such as High or Low DC), the impedance value can be as high as 1 〇 〇ΗΟ ohm, so it can be used as an insulating piezoelectric transformer. Actual operation control ^, when When the load end of the sensed output fails (for example, 〇vp, 〇Cp, etc.), the control circuit (CPU) can be signaled by the abnormal feedback protection circuit to send the DC _, which can be reached to the primary side. The secondary side exhibits a high-resistance state (true insulation). At the same time, because the primary side and secondary side electrode surface areas are large, the capacitance value is large, and a high-power insulating transformer can be used, and at the same time, the first-upper electrode 21 and The second upper electrode 31 has the same shape and is symmetrical to the diameter or center line of the substrate 1 且 and is suitable for LED illumination, backlight cathode cold ray tube (CCFL), back Optical module inverter (|nverte", plane light source (Extema| F|at 円 (10) coffee (10) Lamps, EFFL) female ballast (ballast), or the rest such as notebook computer, table On the electronic device such as the upper computer and personal digital assistant. At the same time, this creation is a single-layer isolation transformer.
