What are the calculation methods for the number of turns of magnetic toroidal inductor?

Toroidal inductor number of turns is one of the important parameters of inductor，The method of calculating the number of turns of magnetic ring inductor is as follows:

1. Mathematical formula method:

Turns N= (magnetic ring length πd +2L)/(line diameter d×π)

Where, D is the outer diameter of the magnetic ring, L is the height of the magnetic ring, and d is the wire diameter of the winding.

2. Actual test method:

By measuring the inductance and current of the coil, the relationship between the inductance and the number of turns can be obtained, so as to calculate the number of turns of the magnetic ring.

3. Simulation calculation method:

The inductance of magnetic ring is numerically calculated by electromagnetic field simulation software, and the inductance turns of magnetic ring are obtained according to the simulation results.

In a word, different calculation methods are suitable for different situations, according to the actual need to choose the appropriate calculation method.
