Abstract
An electronic circuit provided with a piezoelectric transformer for driving an electronic component. The transformer is integrated in the circuit, a first layer of the circuit having a first primary piezoelectric plate integrated therein, a second layer having a secondary piezoelectric plate integrated therein and connected to the electronic component, and an intermediate layer comprising an insulating material is interposed between the primary and secondary plates.
Claims12
An electronic circuit provided with a piezoelectric transformer for driving an electronic component, in which circuit the transformer comprises a primary plate and a secondary plate made from a piezoelectric material, together with an intermediate insulating layer interposed between the primary and secondary plates, the primary plate being arranged to transmit a displacement signal to the secondary plate through the intermediate layer in response to a primary signal that is transmitted to the primary plate via the electronic circuit, and the secondary plate delivering a secondary signal to the electronic component as a function of the primary signal for the purpose of driving the electronic component to which the secondary plate is connected,
- the circuit being characterized by the fact that it comprises a first layer in which the primary plate is integrated and a second layer in which the secondary plate is integrated, the first and second layers being galvanically isolated from each other by the intermediate layer.
