Transformer Turns Ratio Calculator
Calculate the turns ratio n, secondary turns N₂, secondary current I₂, Volts-per-turn, and required core cross-sectional area Ae.
Primary Winding Parameters
Secondary Winding Parameters
Core Parameters (Optional)
Silicon steel: 1.0–1.5 T; Ferrite: 0.3–0.4 T
Results
| Turns Ratio n = N₁/N₂ | — |
| Secondary Turns N₂ | — turns |
| Secondary Current I₂ | — A |
| Apparent Power Rating | — VA |
| Volts per Turn (V/turn) | — V/turn |
| Required Core Area Ae | — cm² |
Formulas
n = V₁ / V₂ = N₁ / N₂ = I₂ / I₁
N₂ = N₁ × (V₂ / V₁)
Ae = V₁ / (4.44 × f × N₁ × Bmax)
