Acoustic galvanic insulating device, has medium permitting transmission of acoustic waves and placed between transformation units comprising ultrasonic transducers, where medium comprises insulator

摘要

The device has a transformation unit for transformation of alternating current voltage into acoustic wave, and another transformation unit for transformation of another acoustic wave into another alternating current voltage, where the transformation units comprise ultrasonic transducers (54A, 54B). A medium permitting transmission of acoustic waves is placed between the transformation units, where the medium comprises an insulator, and a substrate (50) in a form of a glass plate on one face from which insulating layers (52A, 52B) are extended.
