Title: Piezoelectric transformer and method for driving the same
Inventor: KATSUNO YUKIFUMI
IPC: H01L41/107
Filed: 1998-10-29
Abstract: PROBLEM TO BE SOLVED: To improve the efficiency of a piezoelectric transformer over a wide frequency range by providing an inductor connected in parallel with at least one of the input and output-side braking capacitors of an element for piezoelectric transformer. SOLUTION: A piezoelectric transformer is constituted in such a way that a power source is connected to the primary side of an element 10 for piezoelectric transformer containing a piezoelectric vibrating body composed of a piezoelectric ceramic or a piezoelectric single crystal, and a load resistor RL is connected to the secondary side. In addition, for example, an open drum core is connected to the input side of the element 10 as an inductor Lp. When the transformer is constituted in the above- mentioned way, the impedance of the transformer becomes the highest at about 140 kHz, because the inductor Lp causes parallel resonance with a braking capacitor Cd1 on the input side. Consequently, the resonance current of the mechanical system does not change, but only the electric currents flowing to a dielectric resistor and a series resonance resistor change. Therefore, the dielectric loss of the transformer mainly decreases and the efficiency of the transformer is improved over a wide frequency range.
