Abstract

This paper deals with issues of Contactless power converter (CLPC) including converter constitution, circuit model, power transmission and power regulation. Based on a newly developed equivalent load circuit, the influences of contactless transformer (CLT) and its spacing on the energy transmission of the CLPC are investigated. It is found that the relationship between the power transmission and the spacing is not monotonic. Higher level of spacing may result in higher output power or lower output power under different conditions. Experimental results are presented to verify the theoretical analysis.
