1phase-1phasecycloconverter
Abstract :- Single-phase Cycloconverters are used for AC-AC power conversion particular for speed control of AC drives. In this work the Single-phase to single phase cycloconverter is simulated in simulink with the loads as R-Load, RL- Load & 1 phase split phase Induction Motor. Thyristors are used as the power switches during this work.

In this paper, an implementation and dynamic modeling of a three-phase induction motor using Matlab/Simulink are presented in a step-by-step manner. The model was tested by two different ratings of a small and large induction motors. The two simulated machines have given a satisfactory response in terms of the torque and speed characteristics.
