Description
reflected = inductance*ratio², where ratio is target-side turns divided by source-side turns for this reflection convention.
Magnetic coupling uses explicit winding, current and voltage references. Turns-square reflection and mutual-energy signs are ideal model conventions; they do not establish actual coupling, saturation or a safe winding connection.
reflected = inductance*ratio², where ratio is target-side turns divided by source-side turns for this reflection convention.
When to use this tool
Use Transformer Turns Ratio Reflected Inductance when checking one supplied turns-ratio, dot-reference or mutual-coupling term.
How to use the tool and how it works
- Enter inductance, ratio. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read reflected. Use the output convention below.
Require nonnegative inductance and positive ratio. reflected = inductance*ratio², where ratio is target-side turns divided by source-side turns for this reflection convention.1
| Input field | Meaning and units | Accepted input |

| ratio | Target-side turns divided by source-side turns for the stated reflection. | Required. Finite number; strictly above 0. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| reflected | Reflected | Required. Finite number. |

}Limitations and assumptions
- Use henries consistently. This ideal turns-square reflection does not include leakage, magnetizing branches, saturation or frequency-dependent losses.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Numeric signed-zero results are exported as zero.
