Abstract:
1. A magneto-electric transformer, for receiving an external AC electric signal of a given voltage and outputting a stepped up output voltage in response, comprising: a laminated composite core formed of parallel layers, including wherein said piezoelectric layer is sandwiched with a mechanical bond between said first magnetostrictive layer and said second magnetostrictive layer electric section to form the composite core of parallel layers; and output terminals connected to said piezoelectric layer; and a winding having input terminals to receive the external AC electric signal, constructed and arranged with respect to said composite core to generate an alternating magnetic field in said laminated composite core in response to said external AC electric signal flowing though said winding, said arrangement being such that an alternating magnetic flux flows through and induces a magnetostrictive strain in said first and second magnetostrictive layers, wherein said magnetostrictive strain induces a vibration in said first and second magnetostrictive layers at a mechanical frequency, wherein said mechanical bond is constructed and arranged such that said induced vibration of said first and second magnetostrictive layers urges a vibration of said piezoelectric layer, and wherein laminated composite core and said winding are constructed and arranged such that said urged vibration in said piezoelectric layer causes said output voltage across said output terminals, wherein said output voltage is stepped up with respect to said external AC electric signal.
