Abstract
In order to develop a high-performance deflection yoke (DY) for CRTs, a sim ulation system to evaluate the misconvergence and inductance of the DY has been developed. The system can treat the three-dimensional shape and windin g pattern of the DY. In the inductance analysis, the inductance calculation is based on an Integral Equation Method (IEM) and magnetic flux method in which vector potential is integrated along the coils. This method requires no spatial mesh. For calculating the self-inductance, the DY coil is modele d by an equivalent radius model. In this model, several turns of coil are r epresented as one line clement with equivalent radius. As this model can re duce the number of coil elements, the equivalent radius model is effective to reduce calculation time. The system has been applied to the DY. The diff erence between measured and calculated inductance is within 2%. The calcula tion takes place within Ih CPU time using the Hitachi H9000/VR460 (PA-8000, 180 MHz). The shape and winding pattern of the DY fringe can be designed b y the simulation system. (C) 1999 Published by Elsevier Science B.V. All ri ghts reserved.
