Abstract

Contactless transformer is increasingly being used in new applications of contactless electrical applications. It eliminates the metal electric contact restriction that are required in conventional power conversion. The present research is concentrated on a large air-gap transformer in which the power transfer is based on a gap-core arrangement. The control of leakage inductance and leakage field for such arrangement is a very challenging research area. In this paper, a model of the transformer controlled by a set of geometrical parameters and the permeability parameters is proposed. Experimental waveforms and simulation of the proposed air-gap transformer are presented. The length of the air-gap is varied from 0 to 1 cm for this examination. Good agreement has been obtained.
