Design and Simulation of Constant Voltage Variable Frequency Single Phase to Single Phase Cycloconverter in Simulink

Abstract: Cycloconverters convert alternating current of certain magnitude and frequency to another alternating current of another magnitude or frequency. Many of the industrial applications require variable frequency. The cycloconverter plays a pivotal role in achieving this task of supplying variable frequency. There are many types of cycloconverters depending on the number of phases that it is intended to convert the AC voltage to. Simulink is a graphical extension to MATLAB for modeling and simulation of systems. One of the advantages of Simulink is the ability to model a nonlinear system, in which a transfer function is not able to do. Another advantage of Simulink is that, it has the ability to take on initial conditions. In this work, a variable frequency constant voltage cycloconverter will be designed and simulated using Simulink.
