Abstract (en)
[origin: WO2022125094A1] A disconnect switch includes a main switching device including a thyristor configured and operable to selectably close and open a main circuit between a first terminal and a second terminal. A resonant circuit is operatively coupled with the first terminal and the second terminal in parallel with the main switching device and includes a capacitor and switching devices configured and operable to selectably close and open an auxiliary circuit. In a closed state, the auxiliary circuit commutates current from the main circuit through the capacitor and applies a voltage of the capacitor effective to bias the thyristor toward an open circuit state.
