    The program is intended for the automated calculation of the common mode filter chokes.
Calculation Procedure:
1. Select the desired series of the magnetic cores. MSFL - Amorphous based on cobalt in aluminum
       container. MSF is the same in a plastic container. MSFN - Nanocrystalline
       in a plastic container. MSFNP - the same with paint coating.

2. Configure the filter, single-phase or three-phase.
3. Set the desired frequency (10 or 100 kHz) at which the program provides the choke's setpoints.
4. Set the required inductance or impedance of one choke winding to selected frequency. The program calculates the minimum values of the choke inductance.
       The actual value of inductance, taking into account the technological spread according to the technical specifications (-25 / + 40%), may be greater than the calculated value from 0 to + 87%.
5. Set the maximum current value in one winding.
6. Set the gap between the windings if they are separated by a dielectric partition.
       In fact, this is the thickness of the partition.
7. Set the maximum fill factor of the magnetic core window with a wire.
       Clarified practically. In the case when the required number of turns is not placed,
       the fill factor in the source data should be reduced. And vice versa.
8. Set the limit value for current density.
9. Set the maximum ambient temperature.
10.Set the number of the magnetic cores in the package. The default is 1. If you do not provide
   the required parameters, you can increase the number of the magnetic cores in the package.
11. Set the maximum expected temperature of the choke. For MSF series, MSFL the limit value is 100 degrees C. 
For the MSFN series - 155 deg. C. For the MSFNP series - 125 deg. C.
       If for some reason you need to lower the operating temperature of the choke,
       specify the desired value. It should be borne in mind that decrease of the limit operating
       temperature leads to an increase in the size and price of the choke.
12. Set the maximum number of wires in the winding (for design reasons).
13. Press the "Automatic magnetic core selection and calculation" button.
14. The resulting project can be significantly improved manually by changing the parameters in the group
       "Optimization".
15. The program does not take into account the influence of parasitic interturn capacitance of the windings on the impedance of the choke.
     A practical verification of the design in the filter circuit with determination of the actual attenuation is necessary.

  The main work in the program takes place in the "Optimization" group.
Automatic calculation is used when choosing another core or when changing any
source data (outside the Optimization group) to get the starting point for
choke winding data optimization.

     In the "Optimization" group, when changing the values using the arrows, start optimization
begins automatically. But if the new value is entered "manually", then you should run
optimization by the same button.

NOTE - When choosing a series, please note that for thick wires
     the preferred option is in the plastic container. Wire pressure on the aluminum
     container or the paint coating may cause the container deformation or the paint peeling,
     and as a result, the transfer of pressure on the magnetic material with decrease
     of the magnetic characteristics.
