Example Embodiment
[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.
[0017] The topology structure of the current commutated H-bridge hybrid DC fault current limiter is as figure 1 As shown, it includes an on-state low-loss branch, a current commutated branch and four groups of H-bridge diodes. Among them, the on-state low-loss branch includes an ultra-fast mechanical switch and a load transfer switch. The current commutated branch contains three currents. Transfer branch.
[0018] To meet the bidirectional current limiting capability, four groups of H-bridge diode groups are connected in parallel on both sides of the current commutating branch. Under normal conditions, the line current flows from left to right. When a ground fault occurs on the right side of the current limiter, the fault current flows through the two sets of diodes D1 and D4 an...
