Title:
DRIVING METHOD OF PIEZOELECTRIC TRANSFORMER
Document Type and Number:
Japanese Patent JP3734637
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method of driving a piezoelectric transformer which is of four-terminal structure and has a high step-up ratio and a small leakage current even if it is used as a piezoelectric inverter.
SOLUTION: A piezoelectric transformer is equipped with two piezoelectric transformer main bodies 1 and 2, and the primary sides 3 and 4 of the piezoelectric transformers 1 and 2 are polarized in the same direction, the secondary sides 5 and 6 are polarized in opposite directions or the primary sides 3 and 4 are polarized in opposite directions, and the secondary sides 5 and 6 are polarized in the same direction.
