The invention provides a DC current limiter topology, a drive method therefor and a DC current limiter, and relates to the technical field of power transmission and distribution. A DC fault current can be limited, and the probability of phase change failure of a system is reduced. The DC current limiter topology comprises four bridge arms: a first upper bridge arm, a first lower bridge arm, a second upper bridge arm, and a second lower bridge arm. The four bridge arms are respectively formed by the series connection of a plurality of thyristors. The first upper and lower bridge arms are connected in series, and the second upper and lower bridge arms are connected in series. Moreover, a branch circuit formed by the series connection of the first upper and lower bridge arms is in parallel connection with a branch circuit formed by the series connection of the second upper and lower bridge arms. The DC current limiter topology also comprises a reactor and a capacitor, which are connected in series. One end of a branch circuit formed by the series connection of the reactor and the capacitor is connected between the first upper and lower bridge arms, and the other end of the branch circuit is connected between the second upper and lower bridge arms. According to the invention, the technical scheme is applied in a DC system, and a direct current is limited when the system has a fault.
