MAGNETOELECTRIC CURRENT-VOLTAGE TRANSDUCER WITH FREQUENCY DOUBLING Russian patent published in 2018 - IPC H02M5/16 H01L41/83 

FIELD: electricity.

SUBSTANCE: transducer is a structure of a capacitor, the plates of which are made of magnetostrictive metal and mechanically connected to a piezoelectric plate inside and to an inductance coil wound on it, and of a magnetic core, made in the form of two U-shaped plates closely adjacent to the magnetostrictive plates, that ensures the magnetic flux closure. The input signal is the current of the inductance coil, and the output signal is taken from the capacitor plates.

EFFECT: to ensure the transducer's operation, it is not required to create a bias field, and it contains a magnetic core that ensures the magnetic flux closure, which leads to a reduction in energy losses.
