SINGLE SIDED TRANSFORMER BALUN (4:1 impedance match)ĭOUBLE SIDED TRANSFORMER BALUN (4:1 or anything:1 impedance match) WHICH TYPE OF BALUN TO USE - VOLTAGE OR CURRENT VOLTAGE AND CURRENT BALUNS - DIRECT COMPARRISON The need for a balun, some sources of common mode currents and what they are.Ħ) Other definitions of current and voltage balunsĢ) Kirchoff's current law (sometimes called the first)ģ) Kirchoff's voltage law (sometimes called the second)ĥ) VK5AJLs law (an extension of Murphy's) See more on transformers at the bottom of this page.Īir core and magnetic material - experiments to try yourself that demonstrate how various devices actually work. There is simply no difference between a current, voltage or impedance transformer. The only problem I have with the handbook is the labelling of the current transformer. The definitions here are mostly consistent with the ARRL handbook although it's wording is a little confusing. UNBALANCED ↔ BALANCED WITH A BIT OF IMPEDANCE MATCHING THROWN IN
