  1. Comparing with conventional electromagnetic transformer, piezoelectric transformer has many advantages such as compact volume, high step - up ratio, non - flammability and none - electromagnetic pollution, which is an indispensable part in the electronic information system

    壓電變壓器相對于傳統的電磁變壓器具有體積小、重量輕、升壓比高、不易燃、無電磁污染等特點,較好的解決了電磁壓電變壓器體積大、電磁污染嚴重等缺陷,是電子信息系統中不可或缺的重要部件。
  2. However, the inherent shortcoming of piezoelectric transformer hinders its further development. the major problems include : ( 1 ) the development and design of the piezoelectric transformer involve in lots of theoretic aspects including the design of material, dimension, electrode and circuit ; ( 2 ) it is hard to harvest high voltage enhancement ratio and high - power output simultaneously ; ( 3 ) the operation of the piezoelectric transformer is strongly dependent on the resonance frequency, which leads to the difficulty in the design of driving circuit

    但其自身所存在的固有缺點也在很大程度上限制了壓電變壓器的進一步發展,突出的問題有:壓電變壓器的研製包括材料設計、尺寸設計、電極設計和電路設計等多個環節,所涉及的理論面很廣;壓電變壓器的高陞壓比和大功率輸出難以同時得到保證;壓電變壓器的工作過多地依賴于諧振頻率,為外部電路的設計帶來了困難。
