Multilevel voltage source converter |
摘要 |
A multilevel voltage source converter for high voltage DC power transmission and reactive power compensation. The voltage source converter includes at least one phase element including a plurality of semiconductor switches to interconnect a DC voltage and an AC voltage. The voltage source converter also includes at least one auxiliary converter to act as a waveform synthesizer to modify the DC voltage presented to the DC side of the phase element. |

1. A multilevel voltage source converter for high voltage DC power transmission and reactive power compensation, the voltage source converter comprising:
at least one phase element including a plurality of semiconductor switches to interconnect a DC voltage and an AC voltage; and at least one auxiliary converter to act as a waveform synthesizer to modify the DC voltage presented to a DC side of the phase element, wherein the at least one auxiliary converter applies a waveform to the DC side of the at least one phase element, the waveform approximating an offset rectified sinusoid waveform. |
