Power Flow Control: Manages the direction of power flow (motoring or regenerative braking).

Protection: Provides protection against overcurrent, overvoltage, undervoltage, etc.

Examples include rectifiers, inverters, choppers, and AC voltage controllers.

Industrial: Conveyors, pumps, fans, compressors, machine tools, rolling mills, textile mills, paper mills.
Transportation: Electric vehicles, electric trains, trams, elevators, escalators.
Domestic: Washing machines, refrigerators, air conditioners, vacuum cleaners, mixers.
Robotics: Robotic arms, automated guided vehicles (AGVs).
Renewable Energy: Wind turbines (generator control), solar tracking systems.
Medical: MRI machines, surgical robots.

A 1-phase full-wave fully controlled converter (dual converter) uses SCRs to rectify AC to variable DC voltage for a separately excited DC motor armature.
Circuit Diagram: (Imagine a bridge rectifier with 4 SCRs, with the DC output connected to the armature of a separately excited DC motor, and the field winding connected to a separate DC supply).
