Abstract
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.
