High voltage generating device

摘要

A high voltage generating device with a PZT element is disclosed. The device includes an energization control unit for generating an energization voltage, a PZT element unit for performing voltage conversion in response to an output from the energization control unit, and a load unit for receiving an output from the PZT element unit. The PZT element unit is provided with a resonating member and an electrostrictive element, and a period of an output voltage from the energization control unit is controlled so that a primary voltage from the PZT element unit becomes maximum at a timing when the output voltage from the energization control unit is not supplied.
