Difference between current and voltage balun
WebThere are two main modes of baluns: current baluns and voltage baluns. Current baluns operate by forcing equal currents on both balanced lines, effectively eliminating common-mode currents. Voltage baluns force equal voltage on each balanced line; this is ultimately a better fit for impedance matching applications. WebBaluns other than those with a 1:1 transformation ratio, also act as impedance transformer. There are two basic types: voltage baluns and current baluns: Voltage baluns comprise a transformer with at least two sets of windings; they may be interconnected like an auto-transformer. If the input and output section of the transformer has the same ...

WebCurrent baluns, rather than voltage baluns, should be used whenever possible. Current baluns provide better balance and often have lower loss. Current baluns, especially 1:1 ratio baluns, tolerate load impedance … WebNow I m aware of the arguments regarding where the common mode choke should be provided. Some folks insist upon using a 4:1 voltage transformer on the output of the atu to provide a pseudo balanced feed, others say use a 1:1 current balun on the output, and yet more say put a 1:1 current balun on the input.
