MATLAB Simulation of Single-Phase SCR Controller for Single Phase Induction Motor
نویسنده
چکیده
Thyristors are now widely used in many power electronics and motors drives applications. This is due to their several advantages such as relatively small size, low losses, market availability, and low cost. In this paper, a stator voltage control of single-phase induction motor using thyristors is analyzed and simulated. The stator voltage has been controlled by phase angle control of single-phase supply. The delay angles and their corresponding resistor values before the thyristor fires had been analysed. Firing requirements and limits of control have also been studied. An electronic circuit is designed on multisim software with BT 151 thyristor to control the speed of AC induction motor and simulated. The simulation results have been found in correlation with the one obtained from the simulated matlab program using MATLAB 7.

Single-phase induction motors have a wide range of domestic and industrial applications. These motors have a squirrel cage rotor and their stator usually has two windings: main and auxiliary. The use of auxiliary winding in the structure of single-phase induction motors creates two unbalance and asymmetric phases. This causes to increase the spatial harmonics of the field in the air gap, and al...
