In this paper the Electromagnetic disturbances and susceptibility of metallic enclosures which are used in shielding of high voltage industrial power supplies have been studies. Basic parameters in shielding design for uninterruptible power supplies which is important in EMC considerations, have been investigated. The aperture size and position and the distance between two shielded power supplies and their effects on electromagnetic parameters such as electric field intensity, shielding effectiveness, return loss, and resonant modes have been studied. This study is performed by using a new hybrid simulation method that utilizes TLM modelling in near field and Method of Moment in far field.
