Unlike diode rectifiers, phase-controlled rectifiers have the advantage of controlling the output voltage. Diode rectifiers are called uncontrolled rectifiers. When these diodes are replaced with thyristors, then on it becomes controlled phase rectifiers. The output voltage can be controlled by varying the firing angle of the thyristors. These phase-controlled rectifiers have their main application in the speed control of DC motors.
Applications: -
Steel rolling mills, paper mills, textile factories where speed control of DC motors is required.
Electric traction.
High voltage DC transmission
Electromagnet power supplies
