摘要： A piezo ceramic transformer working at a full wave length mode, &lgr;-mode, in accordance with the present invention has a driving region divided into two sections in the center and two generating regions at the end regions of a thin rectangular bar. Two input sections are built into multi-layered structure with multiple internal-electrodes and poled along the thickness direction with polarization in the neighboring layers opposite to each other. Alternating internal electrodes are connected in parallel through two external electrodes in each input section. Polarization in the same layer of two input sections are disposed in the same direction, and two external electrodes of two input sections in the same side of driving region are connected 180 degree out of phase to each other to a driving circuit. Two CCFLs are connected directly to two output electrodes at the end of the piezo ceramic transformer, respectively. Polarization in two output sections is along the length of the piezo ceramic plate, but the respective direction is in opposite way. Alternatively, polarization in the same layer of the two input sections are disposed in opposite direction, and two external electrodes of two input sections in the same side are connected in phase to each other to a driving circuit.

摘要翻译： 根据本发明的以全波长模式工作的压电陶瓷变压器，具有在中心为分为两部分的驱动区域和在薄矩形条的端部区域的两个产生区域。 两个输入部分内置有多层结构，具有多个内部电极，并沿着厚度方向极化，并在相邻的相邻层中极化。 交替的内部电极通过每个输入部分中的两个外部电极并联连接。 在两个输入部分的相同层中的极化被设置在相同的方向上，并且驱动区域的同一侧中的两个输入部分的两个外部电极彼此相位180度相互连接到驱动电路。 两个CCFL分别直接连接到压电陶瓷变压器末端的两个输出电极。 两个输出部分的极化沿着压电陶瓷板的长度，但相应的方向是相反的。 或者，两个输入部分的同一层中的偏振沿相反方向设置，同一侧的两个输入部分的两个外部电极彼此相位连接到驱动电路。
