Abstract
The accuracy of power electronics simulation relies on the semiconductor switch model employed. Thus, in this paper where an ultrafast mechatronic circuit breaker (UFMCB) is implemented in real-time on the field programmable gate array, a detailed nonlinear thyristor model is proposed for extra device-level information regarding design evaluation. The cascaded thyristors impose a heavy computational burden on the UFMCB simulation, and node elimination is achieved following the proposal of a scalable thyristor model. For the convenience of the circuit breaker's integration into dc grid, a pair of coupled voltage-current sources is inserted as its interface, which achieves a reduction in the dimension of system admittance matrix, and the subsequent proposal of a relaxed scalar Newton-Raphson method further expedites the simulation by decomposing the nodal matrix equation. Meanwhile, the modular multilevel converter as a dc grid terminal adopts half-bridge and clamped double submodule topologies to test system performance in conjunction with the UFMCB. Real-time execution is achieved and the results are validated by ANSYS/Simplorer and PSCAD/EMTDC in device- and system-level, respectively.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
