Embodiment Construction
[0045] Please refer to the first figure, which is a schematic diagram of the first embodiment of the piezoelectric power converter applied to the half-bridge input of the present invention, which includes a transformer 11, at least one first piezoelectric component and at least one second piezoelectric component, Among them, the transformer 11 has a primary side 111 and a secondary side 112 . The primary side 111 of the transformer 11 is used as an inductance, and is connected in series with the first piezoelectric component to form a resonant circuit, and the first piezoelectric component is used as a piezoelectric oscillator 12 by utilizing its own capacitance characteristics, and is used for Replaces capacitors in traditional power converters. Among them, the piezoelectric vibrator 12 disclosed in this embodiment, as shown in the second figure A, is a disc-shaped substrate 21 made of piezoelectric material. Of course, its shape can also be square or rectangular or other geo...
