Quick Summary

An impedance-matching transformer is a type of transformer used in electronics to ensure the most efficient transfer of energy between a source and its load. Electrical impedance is the total opposition a circuit presents to electric current, encompassing both resistance and reactance. Reactance arises from changing magnetic and electric fields in alternating current (AC) circuits. By matching the impedance of the source to the impedance of the load, these transformers optimize energy transfer.12
