Abstract
Official abstract text for this publication.
A high-voltage direct-current (HVDC) transmission system includes an alternating current (AC) electrical source and a power converter channel that includes an AC-DC converter electrically coupled to the electrical source and a DC-AC inverter electrically coupled to the AC-DC converter. The AC-DC converter and the DC-AC inverter each include a plurality of legs that includes at least one switching device. The power converter channel further includes a commutating circuit communicatively coupled to one or more switching devices. The commutating circuit is configured to “switch on” one of the switching devices during a first portion of a cycle of the H-bridge switching circuits and “switch off” the switching device during a second portion of the cycle of the first and second H-bridge switching circuits.
First claim
Opening claim text (preview).
What is claimed is: 1. A current source converter-based high-voltage direct-current (HVDC) transmission system comprising: an alternating current (AC) electrical source; and a current source converter (CSC)-based power converter channel comprising: an AC-DC converter comprising a first H-bridge switching circuit electrically coupled to the electrical source, said first H-bridge switching circuit comprising a plurality of first legs electrically coupled in series parallel with r…
