The article is devoted to the study of the high-current AC circuit breaker. The results of the study are presented for various configurations of the arc divider. The study includes methods of spectral diagnostics and high-speed camera shooting synchronized with the electrical characteristics of the circuit breaker (current, voltage) in time. The obtained results allow to determine the composition of the plasma and dynamics of changes in the composition of the discharge in time. Calculation of the plasma composition and properties is made according to the obtained data, which makes it possible to take into account the products of circuit breaker materials ablation in numerical simulation. Non-stationary two-dimensional mathematical model with a moving mesh is developed. The obtained results allow to correct and verify the developed mathematical model of the circuit breaker operation. The evaluation of the arc divider influence is presented in the article.

1700 V/20 mΩ SiC Junction Transistors (SJTs) were recently released by GeneSiC with specific on-resistance as low as 2.3 mΩ-cm2, and current gain > 100. This paper benchmarks the electrical characteristics of the 1700 V SJTs against two best-in-class Si IGBTs. The SJT features 47% and 49% lower on-state voltage drops than the two Si IGBTs, respectively, with the SJT operating at 175°C, and the IGBTs at 150°C. The conduction power loss of the best Si IGBT is 2.2 times larger than the SJT at 25°C, and 1.6 times larger at 150°C. The leakage currents measured on the best IGBT at 1700 V and 150°C is 0.93 mA, as compared to 200 nA for the SJT at 175°C. As compared to the SJT, 3.6x and 3.3x higher (hard) switching energy losses are measured on the best 1700 V Si IGBT, at 25°C, and 150°C, respectively, when switching at a DC link voltage of 1200 V.
