ABSTRACT:
A multiple loads driver circuit equipped with piezoelectric transformation circuits consists of at least one piezoelectric ceramic transformer and two loads connecting to the piezoelectric ceramic transformer(s). Each pair of voltages of the same phase are input to a pair of input ends which have opposite polarization, or the two piezoelectric ceramic transformers group have input ends of opposite polarization or its group assembly output an even number of voltages of opposite phases to input ends of the loads which the feedback ends are grounded respectively.
