摘要： A voltage source converter based high-voltage direct-current (HVDC) transmission system includes a voltage source converter (VSC)-based power converter channel. 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 channel includes a commutating circuit communicatively coupled to one or more of the at least one gas tube switching devices. The commutating circuit is configured to “switch on” a respective one of the one or more gas tube switching devices during a first portion of an operational cycle and “switch off” the respective one of the one or more gas tube switching devices during a second portion of the operational cycle.

摘要： A method for operating a phase-leg of a three-level active neutral point clamped (3L-ANPC) converter is presented. The phase-leg includes an output terminal (120, 122, 124), a plurality of input terminals (114, 116, 118), and a plurality of switches (210, 212, 214, 216, 218, 220) disposed therebetween. The method includes operating the phase-leg in a neutral state (402) to generate an output voltage having a neutral level. The method further includes transitioning the phase-leg to a first intermediate neutral state (404) from the neutral state (402). Moreover, the method includes transitioning the phase-leg from the first intermediate neutral state (404) to a first state (406) to generate the output voltage having a first level. A modulator (112) for operating the phase-leg of the 3L-ANPC converter is also presented. Moreover, a 3L-ANPC converter including the modulator is presented.

摘要： Systems and methods to improve operation of a modular multilevel converter. Some embodiments include a first upper arm with a first active power link module, which facilitates producing a first portion of a first alternating current electrical power at a base frequency and injecting a first even-order current harmonic of the base frequency in the first upper arm, and a first lower arm with a second active power link module, which facilitates producing a second portion of the first alternating current, in which the first portion of the first alternating current and the second portion of the alternating current are combined to facilitate outputting the first alternating current electrical power at a first alternating current terminal, and injecting the first even-order current harmonic in the first lower arm, in which magnitude of the first even-order current harmonic is zero at the first alternating current terminal.
