What are the states of thyristor single-phase controllable rectifier circuit?

Controllable rectifier, bridge semi-controlled rectifier circuit, single-phase bridge semi-controlled rectifier circuit. Thyristor single-phase controllable rectifier circuit has three states, including controllable rectifier, bridge-type semi-controlled rectifier circuit and single-phase bridge-type semi-controlled rectifier circuit, which can adjust the output DC voltage of rectifier circuit. Silicon controlled rectifier (SCR) is a high-power electrical component, also known as thyristor.
