Latest Patents
One of Mancini's latest patents involves a driving circuit for multisectional piezoelectric transformers. This innovative transformer circuit allows for dual inputs that can piezoelectrically interfere with one another, providing adjustable output gain. The circuit utilizes two pulse-position-modulated input signals that are phase-shifted to achieve maximum and minimum gain through constructive and destructive interference. The design ensures that both input signals operate at the resonant frequency of the piezoelectric transformer, optimizing efficiency and reducing power dissipation.
Another significant patent by Mancini describes a lithium niobate piezoelectric transformer operating in a thickness-shear vibration mode. This transformer comprises a lithium niobate substrate with acoustically coupled portions and pairs of primary and secondary electrodes. The configuration allows for a desired voltage transfer ratio by applying an input AC voltage to the primary electrodes, which excites a thickness-shear vibration that produces an output AC voltage.
