Abstract
A strobe apparatus has a discharge capacitor charged by a voltage generated in the output voltage when a piezoelectric transformer is driven in the first resonance mode, and a discharge tube is triggered by a voltage generated in the output electrode when the piezoelectric transformer is driven in the second resonance mode. The transformer has two types of output electrodes and on one surface in the longitudinal direction and two opposing surfaces in the lateral direction. It can be driven by properly switching first and second resonance modes different from each other.
