摘要： PROBLEM TO BE SOLVED: To optimize an electrode structure and to improve electrical characteristics to reduce problems caused by a shape of an electrode.
SOLUTION: A piezoelectric transformer includes an input electrode on a front and a rear surfaces with a lengthwise end side of a piezoelectric ceramic sheet of which main surface is rectangular as a driving portion, and an output electrode on an end face with an opposite side as an output portion. The main input electrode is formed with a length almost half of the piezoelectric ceramic sheet, and a widthwise central portion is formed so that it may curve and protrude towards an output electrode side. Moreover, an auxiliary input electrode is formed which is confronted with the main input electrode on a main surface at a certain space, and which is driven by a reverse phase to the main input electrode. A main driving electrode and an auxiliary driving electrode are driven by the reverse phase. The reverse phase driving is obtained either by connecting to power supply so that the phase may be reversed but with the same polarization direction or by driving through polarization in an opposite direction but at the same phase.

摘要： PROBLEM TO BE SOLVED: To remove the effect of spurious when driving in contour vibration mode.
SOLUTION: An approximately square-shaped piezoelectric ceramic plate is driven by a primary contour vibration with input and output electrodes formed on both sides of a half part and an output electrode formed on the opposite end of the piezoelectric ceramic plate. Conductor strip lines in parallel with the output electrode and connecting center part and end parts in a direction of width are formed on the surface of the piezoelectric ceramic plate of the output side. Spurious is shifted to lower frequency by neutralizing and canceling reverse electric potential generated in the spurious vibration mode with the strip line. Cutting off the corner of the piezoelectric ceramic plate in the input side further improves the effect.

摘要： PROBLEM TO BE SOLVED: To provide a structure which is capable of surely supporting a piezoelectric transformer operating in a contour vibration mode without restraining its vibrations.
SOLUTION: A piezoelectric ceramic board is pinched between a case and a board through the intermediary of an elastic body such as an O-ring so as to keep a gap between the piezoelectric ceramic board, the case, and the board constant. A through-hole is bored in the center of the case and/or the board, and elastic adhesive agent such as silicone adhesive agent or the like is poured into the through-hole and then cured. Vibrations are less restrained, and stress is less concentrated when the silicone adhesive agent is used than the use of soldering, and a mounting structure superior in shock resistance can be realized.
