摘要： The voltage at a spurious frequency is decreased while maintaining as much as possible the voltage at a resonance frequency of a piezoelectric transformer, thus controlling a wide voltage range with a comparatively low cost configuration. A high-voltage power supply apparatus includes a piezoelectric transformer that outputs a highest voltage at a predetermined resonance frequency, and a generating unit that generates a signal that oscillates at a drive frequency that drives the piezoelectric transformer, throughout a frequency range that includes the resonance frequency. Furthermore, the high-voltage power supply apparatus includes an output terminal connected to the piezoelectric transformer, and a constant-voltage element inserted in a path that couples the piezoelectric transformer and the output terminal.

摘要： A piezoelectric transformer includes a piezoelectric element. Two primary side electrodes exist on the primary side of the piezoelectric element. The primary side electrodes are coupled by a resistor formed from a conductive coating. A discharge current is discharged via the resistor to protect a semiconductor component from the discharge current. Since neither a short-circuit terminal nor conductive jig is required, electrostatic discharge damage to a semiconductor component can be prevented by a low-cost arrangement.
