HVDC HVDC Apparatus for controlling switching of HVDC converter and HVDC converter according to cluster stream buffer switching

摘要

The HVDC converter switching control apparatus according to an embodiment of the present invention includes a driver for transmitting an a-phase control signal to a group of a-phase switching elements performing AC-DC conversion or DC-AC conversion of a power system, Phase control signal includes first to nth phase control signals respectively transmitted to n clusters included in the a-phase switching element group, and each of the first to n th phase control signals includes a plurality of switching And the first to nth phase control signals of the first to nth phase control signals are overlapped with the on / off control time of the control signal of the other phase Can have different phases.
