摘要：A high voltage direct current (HVDC) converter system includes a line

commutated converter (LCC) configured to convert a plurality of AC voltages andcurrents to a regulated DC voltage of one of positive and negative polarity and a DCcurrent transmitted in only one direction. The HVDC converter system also includes abuck converter configured to convert a plurality of AC voltages and currents to aregulated DC voltage of one of positive and negative polarity and a DC currenttransmitted in one of two directions. The LCC and the buck converter are coupled inparallel to an AC conduit and are coupled in series to a DC conduit. The HVDC convertersystem further includes a filtering device coupled in parallel to the buck converterthrough the AC conduit. The filtering device is configured to inject AC current having atleast one harmonic frequency into the AC conduit.
