Abstract |
This paper compares two geometries of air core transformer, relevant for high frequency converters andhigh power densities: One logical toroidal, one innovative cylindrical. The manufacturing, the couplingparameter, the volume, and the flux leakage are examined in these topologies. The efficiency symbolizesa crucial parameter on power electronics, and a trade-off must ever be optimized between size andpower. The proposed innovative structure permits to strongly increase the converter power density foran identical efficiency |
