Is a thyristor a DC or AC switch?

A thyristor is primarily considered a DC switch, but it can also be used in AC applications. It allows current to flow in one direction when triggered, making it effective for controlling DC loads. In AC circuits, it can be used for phase control or rectification, but it requires specific triggering and handling due to its ability to conduct in both halves of the AC waveform.

A thyristor is primarily used as an AC switch, but it can be employed in both AC and DC applications. It’s often used in AC circuits for controlling power by allowing current to flow only when triggered by a gate signal and blocking it otherwise. In DC applications, it can function similarly by switching the current on and off, but it’s more commonly associated with AC due to its ability to handle and control high power levels effectively in AC circuits.
