    • A piezoelectric transformer (10) operating in a thickness-shear vibration mode (26). The piezoelectric transformer (10) comprises a lithium niobate substrate (12) having first and second acoustically coupled portions (16,22), and a plurality of substantially opposing pairs of primary and secondary electrodes (14,20) disposed thereon. An input AC voltage applied to the primary electrode pairs (14) exciting a thickness-shear vibration (26) which couples to the secondary electrode pairs (20) producing an output AC voltage therebetween. The primary and secondary electrodes (14,20) being electrically connected in various combinations of parallel and series connections to provide a desired step-up or step-down voltage transfer ratio.
    • 一种以厚度 - 剪切振动模式(26)工作的压电变压器(10)。 压电变压器(10)包括具有第一和第二声耦合部分(16,22)的铌酸锂衬底(12),以及设置在其上的多个基本上相对的初级和次级电极对(14,20)。 施加到主电极对(14)的输入AC电压激励耦合到次级电极对(20)的厚度 - 剪切振动(26),从而在它们之间产生输出AC电压。 主电极和次级电极(14,20)以并联和串联连接的各种组合电连接以提供期望的升压或降压电压传递比。
