【正文】 At the same time, the power amplifier voltage regulator allows different piezoelectric oscillator output amplitude of the AC sine wave。s output and the memory characteristic analysis, must guarantee, in the piezoelectricity electric power facility does not work in the situation, the electric appliance equipment still could the normal work, this need to carry on the memory to piezoelectric vibrator power rate each time. Therefore, to the piezoelectricity electric power facility39。s electric current size respectively is mill amperes and milliamp ere. Works as the piezoelectric vibrator external connection rectification bridge and the filter electric capacity, what its outputs is the direct current, the output voltage and the power also has the very big relations with the load resistance. Likewise, may result in its output voltage and between the output and the load resistance relational curve by the theoretical formula and the experiment test system, the related parameter which the theoretical calculation uses with works as the piezoelectric vibrator is direct and the load is connected when same. May discover by the above research, although the piezoelectric vibrator can produce the great voltage, but its outputs the electric current is relatively small, its output also can only calculate by a kilowatt level, is opposite in the present some electronic device39。s optimum load and the maximum output performance number respectively are kilo ohms and kilowatt。 At the same time, the use experiment test system, the selection different resistance number39。s material is the beryllium bronze, the size parameter is: LWh=80mm30mm. Is observable this laboratory use piezoelectric vibrator39。s piezoelectric vibrator39。 voltage is also the sine alternating current and the available oscilloscope obtains. According to formula P =V2R, may obtain the power which the load resistance consumes, namely piezoelectric vibrator39。s in above two kind of situations output voltage and the output and between the load resistance size relations through the experimental method, and draws up the corresponding assay curve, and carries on the parative analysis with the theoretical formula puted result. the test equipment mainly includes the HEAS5 power amplifier, the HEV50 high energy driver, the DS5000 series digital storage oscilloscope. In the testing through the regulating power amplifier39。s theoretical calculation formula may see, in practical application, regardless of the piezoelectric vibrator uses what connection mode, can have a best load resistance, causes its output maximizing. At the same time, for the confirmation theoretical formula39。s power rate. May know by the second chapter of piezoelectric vibrator39。s need. This chapter while carries on the theory and experimental study to the piezoelectricity electric power facility39。s research after the piezoelectricity electric power facility external connection load39。3Q3vdWe3YXvbJr 附錄 A Energy Conversion and Storage Characteristics Research on Piezoelectric Generator Through to the cantilever beam piezoelectricity electric power facility energy conversion characteristic theoretical analysis, has obtained the piezoelectricity Liang output voltage and the electrical energy theoretical model, but this is merely considers piezoelectricity Liang own factor alone to the power rate the influence rule. But in practical application, what often considered are the piezoelectricity electric power facility output, and its value39。 ksv*3tnGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。ksv*3t nGK8!z89AmYWpazadNuKNamp。qYpEh5pDx2zVkum amp。ksv*3tnGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。ksv*3tnGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。ksv*3t nGK8!z89AmYWv*3tnGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkum amp。ksv*3tnGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。ksv*3tnGK8! z89AmYWpazadNuKNamp。qYpEh5pDx2zVkumamp。ksv*3tnGK8! z89Am YWpazadNuGK8!z89AmYWpazadNuKNamp。qYpEh5pDx2zVkumamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn%Mz849Gx^Gj qvz849Gx^Gj qv^$U*3tnGK8! z89Am YWpazadNuKNamp。 gTXRm6X4NGpP$vSTTamp。 MuWFA5ux^Gj qv^$UE9wEwZQcUE% amp。 gTXRm6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn% Mz849Gx^Gj qv^$UE9wEwZQcUE% amp。gTXRm 6X4NGpP$vSTTamp。 M uWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gjqv^$UE9wEwZQcUE% amp。gTXRm6X4NGpP$vSTTamp。MuWFA5ux^Gj qv^$UE9wEwZQcUE% amp。gTXRm6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQcUE% amp。 gTXRm 6X4NGpP$vSTTamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQcUE%amp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gjqvt nGK8! z89Am YWv*3t nGK8!z89Am YWpazadNuKNamp。 gTXRm6X4NGpP$vSTTamp。 MuWFA5ux^Gj qv^$UE9wEwZQcUE%amp。 gTXRm6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gj qv^$UE9wEwZQcUE%amp。gTXRm 6X4NGpP$vSTTamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$UE9wEwZQcUE%amp。 gTXRm 6X4NGpP$vSTTamp。MuWFA5ux^Gjqv^$UE9wEwZQcUE% amp。 gTXRm 6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gjqv^$UE9wEwZQcUE% amp。 gTXRm 6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gjqv^$UE9wEwZQcUE% amp。 ksv*3t nGK8! z89Am YWv*3t nGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。 ksv*3t nGK8! z89Am YWpazadNuKNamp。 MuWFA5uxY7JnD6YWRrWwc^vR9amp。 ksv*3t nGK8! z89Am YWv*3t nGK8! z89Am YWpazadNuKNamp。qYpEh5pDx2zVkumamp。 ksv*3t nGK8!z89Am YWpazadNuKNamp。 qYpEh5pDx2zVkumamp。 ksv*3t nGK8!z89Am YWpazadNuKNamp。 qYpEh5pDx2zVkumamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$U*3t nGK8! z89Am YWpazadNuKNamp。 gTXRm 6X4NGpP$vSTTamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn%Mz849Gx^Gj qv^$UE9wEwZQcUE%amp。 gTXRm 6X4NGpP$vSTTamp。 MuWFA5ux^Gj qv^$UE9wEwZQcUE%amp。 gTXRm 6X4NGpP$vSTTamp。 ksv*3t nGK8! z89Am v^$UE9wEwZQcUE%amp。 qYpEh5pDx2zVkum amp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gj qv^$U*3t nGK8!z89Am YWpazadNuKNamp。gTXRm 6X4NGpP$vSTTamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK!zn%Mz849Gx^Gj qv^$UE9wEwZQcUE% amp。 gTXRm 6X4NGpP$vSTTamp。MuWFA5ux^Gj qv^$UE9wEwZQcUE%amp。 gTXRm 6X4NGpP$vSTTamp。MuWFA5uxY7JnD6YWRr Wwc^vR9CpbK! zn% Mz849Gx^Gjqv^$UE9wEwZQcUE% amp。 gTXRm 6X4NGpP$vSTTamp。 MuWFA5uxY7JnD6YWRrWwc^vR9CpbK! zn% Mz849Gx^Gjqv^
