The invention discloses a double-twelve-pulse circuit of a direct-current transmission system. The double-twelve-pulse circuit comprises an upper twelve-pulse valve bank and a lower twelve-pulse valvebank which have the same structure,and the upper twelve-pulse valve bank and the lower twelve-pulse valve bank are connected in series and are symmetric in the circuit structure. The twelve-pulse valve banks are connected with an inhibition circuit in parallel,and the purpose of inhibiting high-frequency resonance amplification is achieved. 本发明是种直流输电系统的双十二脉动电路，包括结构相同的上十二脉动的阀组以及下十二脉动的阀组，上十二脉动的阀组以及下十二脉动的阀组串联，上十二脉动的阀组以及下十二脉动的阀组在电路结构中对称，十二脉动的阀组并联有抑制的电路，实现抑制高频谐振放大的目的。
