Title: High voltage generation device
Inventor: KATO KENICHI
IPC: H02J3/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To absorb characteristic variation in a piezoelectric transformer and conduct power control easily by changing a phase difference of input voltage from output voltage for output voltage adjustment. SOLUTION: A high voltage generation device is provided with the power control part of a piezoelectric transformer 3 at a rectangular wave oscillation circuit part 1. The output voltage of the piezoelectric transformer 3 is fed back to the non-reversal input terminal of a computing amplification part 5 through a feedback part 4, and a rectangular wave synchronized with its feedback signal is formed by the rectangular wave oscillation circuit part 1. If a phase difference between the input voltage and the output voltage of the piezoelectric transformer 3 is kept in such an oscillation condition that the piezoelectric transformer 3 is operated at a resonance point, stable driving is conducted at the resonance point, or a point where the output voltage becomes at its peak.  The output voltage can be changed by shifting a phase difference between the input voltage and the output voltage of the piezoelectric transformer 3 from the oscillation condition at the resonance point by a variable resistor 7. It is thus possible to absorb the characteristic variation of the piezoelectric transformer and conduct power control easily.
