PIEZOELECTRIC TRANSFORMER

摘要

PROBLEM TO BE SOLVED: To provide a piezoelectric transformer having a high output power and voltage. SOLUTION: This piezoelectric transformer comprises an exciter 11 having an input electrode 3B and a piezoelectric part 2b and an generator having an output electrode 5 and a piezoelectric part 4, and operates to step up the input voltage applied to the input electrode 3B to obtain an output voltage from the output electrode 5. The piezoelectric part 2 of the exciter is made of a piezoelectric material having a specific dielectric const. different from and layer than that of the piezoelectric part 4 of the generator 12.
