Abstract:
Dense lead zirconate titanate (PZT) ceramics is typically used for fabrications of high power piezoelectric devices. In case of lanthanum and iron ions doping into PZT solid solution (PLFZT), material exhibiting both piezoelectric and magnetic properties can be obtained. Among many investigated compositions particularly the Pb0.91(La0.5Fe0.5)0.09(Zr0,65Ti0,35 )0,9775O3, located near the morphotropic boundary, exhibits the highest magnetoelectric effect. This coupling between magnetization and polarization is achieved by the Fe3+ ions addition that sufficiently rise sensitivity to magnetic field without decreasing the dielectric loss coefficient at the same time. Taking advantage of this specific material the piezoelectric transformer (PT) with magnetic feedback was fabricated, which converts an electrical AC input voltage into ultrasonic vibrations and reconverts back to an output as AC voltage proportionally to the magnetic field intensity. In the present study the unipoled radial mode piezoelectric transformers based on PLFZT-type ceramics prepared by hot-press sintering have been investigated. The effect of the magnetic field on the operating properties was measured for piezoelectric transformer operating at the first resonance frequency.

Abstract:
This paper presents the results of experimental work on thin piezoelectric polyvinylidene fluoride (PVDF) film, used as active layer in piezoelectric transformer. PVDF film was deposited by spray deposition technique on flexible polyethylene terephthalate (PET) substrate and its thickness was measured to be 2 μm. Aluminum (Al) bottom and top contacts were deposited by vacuum thermal evaporation. The transfer function of the transformer was measured at different frequencies in the range 50 Hz – 4 MHz. It was observed that at input frequency of 1 MHz, the transfer function started to decrease, which supposed low-frequency AC/AC transformer. Dielectric losses, which characterize piezoelectric devices’ quality, were less that 0.09 in the whole frequency range. This is proof for the efficient energy conversion and stable operation of the microstructure. The work shows that the PVDF transformer performance is comparable to the existing piezoceramic based transformers, which however suffer of high dielectric losses, signal distortions and relatively low boundary frequency.

Abstract:
A voltage transformer employing the magnetoelectric effect in a composite ceramic heterostructure with layers of a magnetostrictive nickel–cobalt ferrite and a piezoelectric lead zirconate–titanate is described. In contrast to electromagnetic and piezoelectric transformers, a unique feature of the presented transformer is the possibility of tuning the voltage transformation ratio K using a dc magnetic field. The dependences of the transformer characteristics on the frequency and the amplitude of the input voltage, the strength of the control magnetic field and the load resistance are investigated. The transformer operates in the voltage range between 0 and 112 V, and the voltage transformation ratio K is tuned between 0 and 14.1 when the control field H changes between 0 and 6.4 kA/m. The power at the transformer output reached 63 mW, and the power conversion efficiency was 34%. The methods for calculation of the frequency response, and the field and load characteristics of the transformer are proposed. The ways to improve performance characteristics of magnetoelectric transformers and their possible application areas are discussed.

Abstract:
Piezoelectric transformers are electronic devices made from piezoelectric materials. The piezoelectric transformers as the name implied are used for changing voltage signals from one level to another. Electrical energy carried with signals is transferred by means of mechanical vibration. Characterizing in both electrical and mechanical properties leads to extensively use and efficiency enhancement of piezoelectric transformers in various applications. In this paper, study and analysis of electrical and mechanical properties in forms of potential and displacement distribution throughout the volume, respectively, are discussed and especially focused on around its natural frequency. This paper proposes a set of quasi-static mathematical model of electro-mechanical coupling for piezoelectric transformer by using a set of partial differential equations. Computer-based simulation utilizing the three-dimensional finite element method (3-D FEM) is exploited as a tool for calculation in two purposes. The first use is developed the 3-D FEM for identifying its natural frequencies while the second use is for visualizing potentials and displacements distribution within the piezoelectric transformer. The computer simulation based on the use of the FEM has been developed in MATLAB programming environment. In addition, which satisfactory results of natural frequencies are compared with those obtained from the experiment and the accuracy of 3-D FEM model is confirmed.

Abstract:
This paper shown and describe this behaviour an original conceptual design of an electrical transformer. The device it is constituted by an electrodynamic actuator and piezoelectric crystals.The input AC voltage generates an axial vibration in the electrodynamic actuator. The axial vibration is transmitted to a piezoelectric crystal which is polarized in the axial direction and generates the output voltage. In a reduced volumes and a single step, it would be possible to reach voltages of tens of MV and great transformation ratios-achieving these voltages is impossible with conventional systems-The transformer works at axial resonance of the piezoelectric crystal. This device operates to the frequency of order kHz; therefore could be used to generate electromagnetic waves. The capacitive and inductive at its output negligible respect conventional transformer. This transformer could be used in countless devices, such as gamma‐ray machines, electron microscope, solid-state propulsion system, Ion thruster, small particle accelerator etc.

Abstract:
Partial Discharge (PD) is one of the symptoms of an electrical insulation problem, and its permanence can lead to the complete deterioration of the electrical insulation in high-voltage equipment such as power transformers. The acoustic emission (AE) method is a well-known technique used to detect and localize PD activity inside oil-filled transformers. However, the commercially available monitoring systems based on acoustic sensors still have a high cost. This paper analyses the ability of low-cost piezoelectric sensors to identify PDs within oil-filled power transformers. To this end, two types of low-cost piezoelectric sensors were fully investigated using time-domain, frequency-domain, and time-frequency analysis, separately. Thereafter, the effectiveness of these sensors for PD detection and monitoring was studied. A three-phase distribution transformer filled with oil was examined. PDs were produced inside an oil-immersed transformer by applying a high voltage over two copper electrodes, and the AE sensors were coupled to the housing of the transformer. By extracting typical features from the AE signals, the PD signals were differentiated from on-site noise and interference. The AE signals were analyzed using acoustic signal metrics such as peak value, energy criterion, and other statistical parameters. The obtained results indicated that the used low-cost piezoelectric sensors have the capability of PD monitoring within power transformers.

Abstract:
The mathematical model of a piezoelectric transformer of the transverse-transverse type and describes the method of its construction has been presented. Although mathematical modeling programs for piezoelectric devices can achieve any predetermined modeling accuracy, the simulation results cannot be directly used in the development of electronic equipment, because the programs are not integrated with CADs, for this reason most often in calculations and in modeling circuits based on piezotransformers, the simplest equivalent circuit is used. But its adequately reflects currents and voltages in the piezotransformer circuit only in the vicinity of the operating resonant frequency. The proposed model is based on a one-dimensional approximation of the equations of state and dynamics of the piezoelectric medium for flat plates of constant thickness and width, which is obtained from a three-dimensional system of equations by averaging the width and thickness. While the usual approximate model often allows to model a piezotransformer with two pairs of electrodes and only in the vicinity of one resonant frequency, the model constructed in the article allows to take into account the presence of several electrodes on piezotransformer surfaces and their different relative positions on the upper and lower surfaces. 'esoplastin. Compared with the usual, the proposed model is more convenient for modeling by means of circuit modeling systems. In the developed model, the piezotransformer is represented as a set of interconnected sections that carry one pair or several pairs of electrodes on the surfaces. Also, in contrast to the usual, the proposed model allows to take into account the presence of several resonant frequencies of the piezotransformer, which allows more adequate modeling of electronic equipment that uses in its structure a piezoelectric transformer of the transverse type. On the basis of the mathematical model the scheme of substitution of separate sections of the piezoelectric transformer is constructed and formulas for calculation of parameters of elements of the scheme are given. In in the article as example the implementation of the developed model in the computer-aided design system MicroCAP has been showed.

Abstract:
With the rapid application of internet of things technology and wireless sensor in transformer station, the demand for stable and reliable power source becoming increasingly stronger. Power transformer operates with high energy density vibration, which provides a suitable energy source for health monitoring sensors. A cymbal piezoelectric transducer is designed to harvest the energy of vibrationwhich is made of cymbal end cap and piezoelectric ceramic to convert mechanical energy to electricity. Also, the power circuit is designed to realize the transmission and storage of electric energy. Then, the performance of the cymbal piezoelectric energy harvester is explored by FEM and experiment. The influence of mechanical vibration characteristics on the charging power of piezoelectric transducer is studied, including amplitude, frequency and preload. The experimental results show that the cymbal piezoelectric energy harvester can provides stable and reliable power, which allows the possibility of large-scale application of wireless sensor in transformer station. The present work provides a new design concept for developing the novel cymbal harvesters used in large-sized vibratory equipment, such as power transformer, to harvest vibration energy.
