Overview
Closeup |
Estimating the size of the inductance for a transformer is vital during
the design process. It is advantageous to measure the leakage inductance
using a simulation as it is difficult to calculate by hand.
This example presents the use of a magnetic field analysis to obtain the
self-inductance and leakage inductance of a transformer when the arrangement
of the secondary coil is modified. |
Inductance
| The inductance of the transformer when the secondary coil has a uniform
coiling and close coiling is indicated in Table 1. The model that has a
secondary coil with a closed coiling has a larger leakage inductance. |

Evaluating the Leakage Inductance
Closeup |
The flux linkage of the primary coil is evaluated as the flux leakage because
the magnetic flux produced by the primary coil is eliminated by flux linkage
of the secondary coil. The variations of the flux leakage versus time can
be evaluated from the voltage terminal of the primary circuit. |
