    Disc piezoelectric ceramic transformers

  • Original language description

    In this contribution, we present our study on the discshaped and homogeneously poled piezoelectric ceramics transformers working in various planar-extensional vibration modes. Transformers are designed with electrodes divided into wedge, axisymmetrical ring-dot, moonie, Smile or Jin-Jiang segments. Electrodes are designed on one side of the transformer; opposite side is fully electroded. A set of transformers with different electrode pattern has been prepared from hard PZT ceramics (type APC841, diameter 20mm, thickness 0.8mm). Transformation ratio, efficiency, input and output impedance were measured for low-power signal. Transformer efficiency and transformation ratio were measured as a function of frequency and impedance load in the secondary circuit. Parameters were further measured for the fundamental and second resonance. Optimum impedance for the maximum efficiency has been found. Maximum efficiency and no-load transformation ratio can reach almost 100% and 52 for the fundamenta
