Toroidal Transformer- To compare with the traditional EI Transformer, the Toroidal Transformer has the advantages of small size, low magnetic leakage, high efficency, internal resistance is samll and fast raction. To compare the Toroidal Transformer with the same power of ordinary transformer, the volume and weight can be reduced 25-30%, while the efficiency is up to 90% or more, (ordinary transformer usually about 80% ).
