Webb10 okt. 2024 · A thyristor is a four-layer device with alternating P-type and N-type semiconductors (P-N-P-N). In its most basic form, a thyristor has three terminals: anode … Webb1 jan. 2014 · In order to simplify the protection circuit, we propose a new circuit using thyristors shown in Fig.2. When the superconducting coil is in superconducting state, the thyristors turn on, and transport current is supplied to the coil. When the quench occurs in the coil, the thyristors turn off, and the transport current is cut off.
