The contactless transformer is an important requirement for the industrial applications. It eliminates the metal contact restriction for power conversion. The present research is concentrated on the large air-gapped transformer such that the power transfer is based on such arrangement. The leakage inductance and the leakage field is the challenge. A model of the transformer., the experimental waveforms and analysis of a power converter based on the gapped-transformer are presented. The length of air-gapped has been increased to 1cm and the performance is satisfactory. Design criteria and consideration is also presented and discussed. Two converter based on the contactless transformer were built and tested.
