1. a piezoelectric power supply converter, it comprises:

  • One transformer, has primary side and secondary side;

    At least one the first piezoelectric element for electric energy conversion, be a piezoelectricity oscillator or an insulated type piezoelectricity oscillator, the effect electricity resistance ﹑

    equivalence inductance ﹑

    such as the equivalent electric circuit of this piezoelectricity oscillator comprises and the equivalent capacity of electrical characteristics and the equivalent capacity of mechanical characteristic, the capacitance of the equivalent capacity of this mechanical characteristic is 3 times of capacitances of the equivalent capacity of these electrical characteristics, this the first piezoelectric element system one end is connected to this primary side, and other end system receives a continuous pulse wave voltage and exports an electric signal to this primary side;

    At least one second piezoelectric element is be positioned at this secondary side, and changes for electric energy and export a direct voltage and operate to external loading;

    AndAlso comprise a resonant inductance, it is connected in series in this first piezoelectric element to form a half-bridge resonant circuit, and is positioned at this primary side of this transformer.
