摘要：A voltage source converter based high-voltage direct-current (HVDC)transmission system includes a voltage source converter (VSC)-based power converterchannel. The VSC-based power converter channel includes an AC-DC converter and a DC-AC inverter electrically coupled to the AC-DC converter. The AC-DC converter and a DC-AC inverter include at least one gas tube switching device coupled in electrical anti-parallel with a respective gas tube diode. The VSC-based power converter channelincludes a commutating circuit communicatively coupled to one or more of the at leastone gas tube switching devices. The commutating circuit is configured to “switch on” arespective one of the one or more gas tube switching devices during a first portion of anoperational cycle and “switch off” the respective one of the one or more gas tubeswitching devices during a second portion of the operational cycle.
