Method to Maximise Utilisation Rate of Flux Linkage in Coreless Transformer
A coreless transformer (CLT) with a maximum utilisation rate of flux linkage is proposed. Compared to existing CLTs, the proposed CLT operates at a significantly lower frequency of 100 kHz, and there is no need for superconductors. Compared with the magnetic‐core transformer (MCT), the proposed CLT has almost the same efficiency, while the gravimetric ...
