Please refer to the ninth figure for the high power output piezoelectric of the creation: :=:::======= Work: ^ M368236 will generate a positive charge, so that the voltage is amplified, so the square wave AC pulse signal can be converted into a sine wave high AC voltage and then output to the filter rectifier Circuit 15. The filter rectifier circuit 15 converts the AC voltage whose direction and magnitude are alternating into a DC voltage according to the received high AC voltage as a positive half cycle or a negative half cycle, and then outputs the DC voltage to the external load by the first piezoelectric capacitor 17 . The 'insulated piezoelectric oscillator 80 has a small leakage current (about 0 to 〇.2 to eight), which has the advantages of improved conversion efficiency, high pressure resistance, high temperature resistance, good insulation, small volume, and thin package thickness. Therefore, compared with the two capacitors in the general full-bridge resonant circuit, it has a higher efficiency. As shown in the tenth and tenth drawings, the tenth diagram is a cross-sectional view of the insulated piezoelectric oscillator. The tenth B is the equivalent circuit of the insulated piezoelectric oscillator. The insulating piezoelectric oscillator 80 includes a substrate 81, at least one first upper electrode 811, at least one first lower electrode 813, at least one second upper electrode 812, and at least one second lower electrode 814.

When operating at the same resonance frequency point of the spectral inductance U, U and the insulating piezoelectric oscillator 80, the internal impedance is the smallest and the current is the largest, and the insulating piezoelectric oscillator 8 produces a piezoelectric effect and the square wave is connected to the alternating current pulse. The wave signal is converted into a high AC voltage of a sine wave, and the first output terminal 803 and the second output terminal 804 of the insulated piezoelectric vibration absorber 80 respectively output a high AC voltage to the filter rectifier circuit 15. Due to the piezoelectric effect, the capacitance can be increased several times. In addition to improving the power conversion efficiency, it can be used as a high-power output. Therefore, when operating at the resonant frequency, the full-bridge resonant circuit of the present invention can output more power than the half-bridge | In addition, this creation can parallel or series connect multiple insulated piezoelectric oscillators 80 to increase its conversion efficiency. It can be known from the above that this creation does not require the use of a huge coil type step-up transformer.

For the performance, please refer to the fourteenth figure. It is the eighth implementation of the high-power output voltage converter of the creation of Zhejiang, and its _13 figure is that it has two third piezoelectric 70 pieces and the power switch circuit is a full-bridge power switch. The circuit 14 and the two first piezoelectric 70-pieces replace the two capacitors of the _-like full-bridge contact circuit, and are located at the output end of the full-bridge power switch circuit 14, and the second-piezoelectric elements are respectively - the first piezoelectric The shaker 41 and the second electric shocker 42. The first electric shock absorber 41 and the second piezoelectric vibrator 42 receive power_the circuit 14 outputs a square wave-AC pulse signal, and after the piezoelectric effect, the AC pulse signal can be converted into a high AC voltage. After the external load operation, the first piezoelectric vibrator 41 and the second piezoelectric vibrator 42 _ piezoelectric effect, the first piezoelectric vibrator 41 and the second piezoelectric vibrator 42 are divided into high capacitance # In order to provide a multiplier of increased output power 'S', this is the ability to provide high-power output. Continuation' Please refer to the fifteenth figure, which is a schematic diagram of a ninth embodiment of a piezoelectric power converter of high power output. A resonant inductor L1 is added to the hybrid circuit of the H-type wiper, and f is located between the half-bridge power switch circuit 14 and the first piezoelectric vibrator 41 to form a half bridge resonant circuit. The oscillating inductor u is an AC pulse signal outputted by the receiving power switch circuit 14. Since the resonant inductor u has a boosting and energy storage function, it can provide a higher impurity conversion efficiency of the 14th M368236-piezoelectric shock 41. After the electrical effect, the AC pulse signal output from the power switch circuit 14 can be converted into a high AC voltage to the external load. Of course, if two resonant inductors U and L2 are added and connected in series to the first electrical oscillator 41 and the second piezoelectric oscillator 42 to form a full bridge resonant circuit, the power output is as shown in FIG. Show. For the continuation, please refer to the seventeenth embodiment of the eleventh embodiment of the piezoelectric power converter of the high power output of the present invention. The power converter is characterized in that two piezoelectric oscillators are arranged side by side to form an insulated piezoelectric oscillator 8 〇 which is used to replace the two capacitors of a general full bridge resonant circuit. The insulated shock disk 80 is used on the full-bridge resonant circuit of the power converter of the present invention, and is located at the wheel end of the full-bridge power switch circuit. The insulated piezoelectric shock absorber H 8G system receives the power pulse circuit 14 to output the AC pulse signal of the square wave. When operating at the resonance frequency, the insulated piezoelectric oscillator 8 is used for storing electric energy and has piezoelectric characteristics, which can be adjusted. The power factor will output the power again. When the power is deformed, the reverse power consumption effect will be generated. After the deformation, the positive piezoelectric effect will be generated, and the conversion of the positive and negative piezoelectric effects will generate a positive charge, so that the voltage is amplified, so the square can be The wave pulse signal of the wave is converted into a high AC voltage of a sine wave and then output to an external load operation. In addition, if a two-spectrum 'inductance^ and L·2 are added and a full-bridge power switching circuit μ and an insulated piezoelectric oscillator are formed, a full-bridge spectral circuit is formed, wherein the spectral inductance ^ U corresponds to the first input terminal 801 and the second input terminal 8〇2 connected in series to the absolute piezoelectric absorber. The spectral oscillator and the L2 receive power switching circuit 14 output a square wave AC pulse signal. Since the resonant inductors L1 and U have a boosting and energy storage function, the piezoelectric piezoelectric oscillator can be provided with higher voltage conversion efficiency. . When operating at the same resonant frequency point of the resonant inductor 1_1, (_2 and the insulated piezoelectric oscillating 咢, the internal impedance is the smallest and the current is the largest, and the insulating piezoelectric oscillator generates the piezoelectric effect and converts the square wave AC pulse signal. It is a high AC voltage of a sine wave, and a high AC voltage is output from the first output terminal 8〇3 and the second output terminal 2〇4 of the insulated piezoelectric oscillator 80 to an external load, as shown in FIG. In the above embodiment of the power converter applied to the AC to AC, the second piezoelectric shock absorber can be arranged side by side as an insulating surface electric shock device, which is used to replace the general full bridge spectrum 15 M368236 vibration circuit.
