Method for performing communication between primary and secondary sides of transformer, involves generating alternating current voltage during transmission of signal to primary side by modulating amplitude and current of primary side

摘要

The method involves modulating reactance of a secondary side (II) during transmission of signal from the secondary side to a primary side (I). An alternating current (AC) voltage is generated during transmission of the signal to the primary side by modulating amplitude and current of the primary side. The reactance is modulated by switching a capacitor (7) connected in parallel to a load (5). An independent claim is included for a device for performing communication between primary side and secondary side of transformer.
