DC power transmission systems and method of assembling the same

摘要

A DC power transmission system is configured to generate an electric field including components substantially constant with respect to time and varying with time. The DC power transmission system includes an AC stage configured to receive AC electrical power. The AC stage includes a transformer including primary windings and secondary windings configured to be electromagnetically coupled to, and electrically isolated from, each other. The AC stage also includes an AC/AC converter having substantially no insulating features against the at least one substantially constant component of the electric field. The AC/AC converter is electrically coupled to the primary windings. The DC power transmission system also includes an AC/DC conversion stage positioned downstream of the AC stage. The AC/DC conversion stage includes an AC/DC rectifier configured to convert AC electrical power to DC electrical power without external control. The AC/DC rectifier is coupled to the secondary windings.
