摘要： A multi-layer piezoelectric center-drive ceramic transformer includes a stack of piezoelectric ceramic blanks sintered together, each piezoelectric ceramic blanks having at least one odd-number layer and at least one even-number layer alternatively sandwiched in between a top cover layer and a bottom cover layer, first and second inner electrode layers reversely printed on the at least one odd-number layer, third and fourth inner electrode layers reversely printed on the at least one even-number layer, first and second output terminal electrodes respectively printed on two distal ends of each piezoelectric ceramic blank, and first and second input terminal electrodes respectively printed on two opposite lateral sides of each piezoelectric ceramic blank, the first input terminal electrodes being respectively connected to the first inner electrode layers and the third inner electrode layers, the second input terminal electrodes being respectively connected to the second inner electrode layers and the fourth inner electrode layers.
