Lightning-Resistant Power Transmission System

A system includes a first converter coupled to a first ac source, wherein the first converter is configured to convert a first ac voltage of the first ac source into a first ac current, a transmission line loop connected between two output terminals of the first converter, wherein the first ac current is configured to flow through the transmission line loop, and a second converter coupled to the transmission line loop, wherein the second converter is configured to convert the first ac current into a voltage fed into a load coupled to the second converter.
