Abstract
The present invention relates to a multi-pulse HVDC system which is capable of minimizing the number of thyristors by providing a thyristor auxiliary circuit in a conventional 12-pulse thyristor HVDC(High Voltage Direct Current), not using an additional stack of a thyristor and which is implemented based on an auxiliary circuit having a multi-pulse thyristor HVDC system like 24-pulse/36-pulse/48-pulse converters. The multi-pulse HVDC system is characterized in that an upper side thyristor converterand a lower side thyristor converterare installed in a Δ-Δ-Y transformer, and two current smoothing reactorand a direct voltage dividing condenserare installed between the upper side thyristor converterand the lower side thyristor converter, and two thyristors: Tand Tare connected to one double winding transformer
