Abstract

See full text

Disclosed is a digital chip-based digital driving method for a piezoelectric ceramic transformer, comprising the following steps: in a case where there is a variation in temperature and/or humidity, acquiring an output voltage of the piezoelectric ceramic transformer after rectification via a high voltage sampling circuit; sending the acquired output voltage signal to a single chip microprocessor DDS generator, comparing the acquired output voltage with a preset voltage by the single chip microprocessor DDS generator, and adjusting the frequency of the driving signal in a case where a difference between the acquired output voltage and the preset voltage exists; and adjusting a boost ratio of the piezoelectric ceramic transformer by the frequency of the driving signal, so as to output the preset voltage by the piezoelectric ceramic transformer.
