Cyclo converter using thyristors can be used to control the speed of Induction motor. This system is a very complicated solution to control the induction motor’s speed particularly for single or 3-phase ac motors. In our daily life, AC motors are mostly used in various applications like domestic as well as industrial level. The applications of these motors mainly include water pumps, vacuum cleaners, and washing machines. The speed control of these motors is difficult due to invariable.
Here, we are going to discuss a cyclo converter using thyristors for driving the single-phase induction motor, whose cost would less be as compared the other motor drivers. Through by using this system, the motor speed could be controlled. This system would be made with the help of microcontroller AT89S51/52, LM358, optocouplers, SCR, and semiconductor switches such as thyristors.
