Abstract
The present invention discloses a high-voltage lamp-ignition piezoelectric oscillator, wherein a piezoelectric capacitor is connected to an LC resonance circuit in parallel to transform power. The LC resonance circuit is used to generate resonance. Voltage is applied to the piezoelectric capacitor to deform the piezoelectric material due to the inverse-piezoelectric effect and then generate electricity after deformation due to the piezoelectric effect. The combination of piezoelectric and inverse-piezoelectric effects generates additional charge and boosts the voltage. Thereby, the present invention decreases power consumption and reduces cost.
