WebThe CL-CB consists of high-speed mechanical switch, solid-state switch e.g., gate turn-off thyristor (GTO), snubber circuit and voltage protection element e.g., zinc oxide (ZnO) arrester. This is considered a common topology of CL-CB. After twenty-three years of progress, solid-state switches are changing to insulated-gate bipolar transistors ... WebSep 9, 2024 · A normal thyristor or conventional thyristor is used as an ideal switch for power electronic circuits. for on this thyristor, there is gate signal is provided but for off the device, there is the use of a communication circuit that enhances the prices of circuits and makes it heavyweight. To overcome these features GTO was introduced.

WebDescription. The GTO block models a gate turn-off thyristor (GTO). The I-V characteristic of a GTO is such that if the gate-cathode voltage exceeds the specified gate trigger voltage, the GTO turns on. If the gate-cathode voltage falls below the specified gate turn-off voltage value, or if the load current falls below the specified holding ...
