Abstract
A method of making a piezoelectric transformer (100) comprising a primary plate (4) and a secondary plate (8), in which a step a) is implemented during which, on the basis of an equivalent model of the transformer (100), a geometrical parameter for the plates or a physical parameter for a material constituting the plates is determined, while taking account of an expression for the heat dissipated by losses in the transformer.
Claims20
A method of making designing a piezoelectric transformer comprising a primary plate and a secondary plate the method comprising:
- designing at least one geometrical parameter of the plates or at least one physical parameters of a material constituting the plates or a combination of at least one geometrical parameter of the plates and at least one physical parameter of the material by taking into account an expression for heat dissipated due to losses in the transformer.
A method of designing a piezoelectric transformer comprising:
- designing primary and secondary plates of the transformer such that a thickness of the plates, a surface area of the plates and a material from which the plates are fabricated, all are determined by taking into consideration heat dissipation as a result of power loss during operation of the transformer and a maximum acceptable operating temperature of the transformer;
- assembling said two plates on either side of an intermediate layer of the transformer, said intermediate layer comprising an electrically insulating material;
- and
- applying primary and secondary metallization to said plates, the primary metallization being for connection to a primary circuit and the secondary metallization being for connection to a secondary circuit;
- wherein the intermediate layer of the transformer is mounted on a rigid support secured to an electronic circuit medium supporting said primary circuit and said secondary circuit.
