Compared to bloated and bulky portable devices, consumers hope that the product design is not only thin and light, but also easy to operate. There is also a long battery life. Consumer preferences have created a dilemma for circuit design engineers: they must provide more power to the system and generate more sets of dust, but at the same time 'portable products are available for power supply space and batteries The capacity is decreasing. In order to meet these technical requirements, designers must use higher power efficiency. However, the general-purpose power supply circuit towel uses a capacitor in series or in parallel with the inductor to make the vibration effect. The low capacitance, excessive voltage signal, will cause a large leakage current, the efficiency of the output is not high, and the capacitance H (four) pressure is insufficient, the failure mode will cause the capacitor H to explode, resulting in the risk of fire. In view of this, the present author proposes a deficiency in the prior art of a piezoelectric power converter. [New content], in order to improve the existence of the single purpose is to provide a piezoelectric power converter, using the structure to achieve the transformer 'to provide multiple increase in wheel power, and then = 2 = ^ = ·: = plant coffee The surface structure is simple and has the danger of fire. It has high reliability, which can solve the problem of low pressure resistance and overheating and ignition caused by the electric 3 M366832 container in the conventional power converter. Secondly, the piezoelectric element is small in size and package thickness. Thin, extremely competitive in the market. In order to achieve the above object, the present invention provides a piezoelectric power converter for an AC to DC power converter, comprising a transformer having a primary side and a secondary side, at least one of the first piezoelectric elements being connected to one end at a time. The other end receives a pulse voltage and rotates to the primary side. At the output end, at least one second piezoelectric element is disposed on the secondary side, and is used for outputting the DC voltage to the external load. In addition, the present invention provides another piezoelectric power converter for an AC to AC power converter, comprising a transformer having a primary side and a secondary side, at least one of the first piezoelectric elements being connected to the primary side at one end The other end receives a pulse voltage and outputs it to the primary side, and the secondary side outputs an alternating voltage to an external load. The purpose of the present invention, the technical content, the features, and the effects achieved can be more easily understood by the specific embodiments and the accompanying drawings. [Embodiment] Please refer to the first figure, which is a schematic diagram of a first embodiment of a piezoelectric power converter applied to a half bridge input, comprising a transformer 11, at least a first dust electric component and at least a second Piezoelectric 7G piece 'where the transformer 11 has a primary side and a secondary side 112. The first side 111 of the transformer is used as an inductor, and the -piezoelectric element is connected in series with the first piezoelectric element to form a -resonant circuit', and the electric property of the first pressure-fit member paste itself is used as a piezoelectric oscillator 12. And replace the capacitor of the traditional lion converter towel. In the basin, the piezoelectric vibration 12 disclosed in the embodiment is as shown in the second A diagram, and the substrate 21 of the electric material is produced - the shape of the substrate may be square or rectangular. The shape 'will be made of silver glue, copper paste or brocade to form the circular electric layer 22, 23 on all or part of the upper surface and the lower surface of the substrate 21 to form the two poles of the electric shock absorber 12 to guide the current. . Here, please refer to the second B diagram, for the equivalent circuit effect circuit of the magic electric oscillator 12, the equivalent resistance R, the equivalent inductance L, and the equivalent capacitance Ca and Cb respectively indicating the electrical and mechanical characteristics. . In this embodiment, a transformer can be used, and the sub-side, j M366832 is used as an inductor to form a half-bridge resonant circuit. When the resonant circuit resonates, the piezoelectric oscillator 12 is used to store electrical energy and has piezoelectric characteristics, and the power can be adjusted. The factor will then produce an inverse piezoelectric effect when the power output is energized and deformed, and a positive piezoelectric effect will occur after the deformation, and the conversion of the positive and negative piezoelectric effects will generate a positive charge, which will amplify the voltage and have an amplified voltage. The effect is to achieve the effect of high-power output, wherein the mechanical characteristic Cb value of the equivalent capacitance in the equivalent circuit is about 3 times the capacitance of the electrical characteristic ca value, and the capacitance of the ca value and the cb value are added, so The piezoelectric oscillator 12 has a high capacitance (Q=C*V), so that the output power of the multiple is increased, thereby improving the efficiency of the energy conversion. The second piezoelectric element is located on the secondary side 112, and the second piezoelectric element is used as a -burg capacitor 13 by its own capacitive characteristic and is used to replace the capacitor in the conventional power converter. The piezoelectric capacitor 13 disclosed in the embodiment is an equivalent circuit of the piezoelectric capacitor 13 as shown in the second C diagram. The equivalent circuit has an equivalent resistance R, an equivalent inductance L, and an electric representation. The equivalent capacitance of the characteristic ca. The difference between the piezoelectric oscillator 12 and the piezoelectric capacitor 13 of the present embodiment is that the leakage current is small, the pressure resistance is high, and there is no risk of overheating and igniting, and the reliability is high, and the conventional power converter can be solved. In the capacitor, the voltage is low and the risk of overheating is caused. In addition, since the piezoelectric oscillator 12 and the piezoelectric capacitor 13 are small in size and thin in package thickness, they have a market competitive advantage. The two sides 112 of the transformer 11 are respectively connected to the diodes D1 and D2, and the diodes D1 and D2 are connected to a filter inductor 14, and the second piezoelectric element is connected to the filter inductor 14 An output filter rectifier circuit is formed. Since the diodes D1 and D2 have the characteristics of unidirectional conduction, the alternating voltage of alternating direction and size can be converted into a direct current voltage, so that it is used for rectification. When the input voltage of the primary side 111 is positive, the input voltage of the secondary side 112 is also positive. When the input voltage is positive half cycle, the upper end of the secondary side 112 of the transformer turns positive and the lower end is negative, the diode D1 is forward biased, and current can flow from the diode D1 through the filter inductor 14 to The piezoelectric capacitor 13 is charged, but the diode D2 is reverse biased, which corresponds to an open state, and no current flows. When the input voltage is negative half cycle, the upper end of the secondary side 112 of the transformer turns negative, and the lower end is positive, the diode D1 is reverse biased, the electric M366832 flow cannot flow, and the diode D2 is forward biased. The voltage and current can be discharged from the diode Zhao D2 through the filter inductor 14 to the piezoelectric capacitor 13, whereby the piezoelectric capacitor 13 is used to output a DC voltage to an external load. Please - and refer to the first and third figures. The third figure is a schematic diagram of the second embodiment of the piezoelectric power converter applied to the full bridge input, which is the same as the embodiment of the first figure, and the similarities are not repeated. The difference is that there are two first piezoelectric elements which are used as the first piezoelectric oscillating device 31 and the second piezoelectric oscillating device 32, and are located on the primary side 111 of the transformer 11 The primary side of the dust filter 11 is used as an inductor to form a full bridge resonant circuit. The piezoelectric oscillators 31 and 32 are respectively connected to the two ends of the primary side 111, and the first electric shock disk 31 and the second piezoelectric shock are respectively connected. The device 32 receives the pulse voltage. When the vibration circuit is oscillated, it generates a piezoelectric effect and increases the capacitance and outputs it to the primary side 111, which improves the power output more than using a piezoelectric oscillator. Please refer to the third and fourth figures together. The fourth figure is a schematic diagram of the third embodiment of the piezoelectric power converter applied to the full bridge input, which is the same as the embodiment of the third figure, and the similarities are not repeated. Wherein the difference is that the transformer 1 has at least one center tap 41' and is located in the middle of the secondary side 112, and the voltages at the center tap 41 to the ends are equal. When the input voltage is positive half cycle, the diode D1 is forward biased, and current can flow from the diode D1 through the filter inductor 14 to the piezoelectric capacitor 13 for charging, and then return to the center tap 41 ' but the diode D2 is a reverse bias, which is equivalent to an open state, and no current flows. When the input voltage is negative half cycle, the diode D1 is reverse biased, the current cannot flow, and the diode D2 is forward biased. The current can flow out from the diode D2 through the filter inductor 14 to the piezoelectric capacitor 13 Charging is performed and then returned to the center tap 41. Therefore, the polarity of the voltage drop generated on the piezoelectric capacitor 13 is the same as that in the positive half cycle, that is, the current through the piezoelectric capacitor 13 is the same direction, and then the piezoelectric capacitor 13 output DC voltage to external load operation. Please refer to the fourth figure and the fifth figure together. The fifth figure is a schematic diagram of the fourth embodiment of the piezoelectric power converter applied to the full bridge input, which is similar to the embodiment of the fourth figure, and the similarities I will not repeat them. Among them, the difference lies in the inclusion of the first spectral inductance 51 M366832
