	The program - calculator is intended for the automated calculation of single-turn and multi-turn noise suppressing chokes. The program is designed to calculate the most widespread case of application of noise suppressing chokes, when the choke is connected in series with the diode. The choke changes the diode switching mode, makes it “softer", sections with steep fronts are excluded and due to this, the noise is sharply weakened. The program is implemented common for two groups of the magnetic cores produced by PC «MSTATOR». 
	MSB-series (MSB Series Bead).  These are small-sized cylindrical magnetic cores from an amorphous cobalt-based alloy with annealing without field. Saturation induction is 0.6 T. They have a rectangular hysteresis loop. They are structurally optimized for putting directly on the component taps. This results in a single-turn noise suppressing choke. In this regard, the program does not calculate the number of turns and the diameter of the wire. The program selects the required size and number of the magnetic cores (maximum up to 4, per two for each tap of the diode). Temperature range is from - 60 to 100°C.
	MSK-series (Series Spike Killer). The same Co-based amorphous alloy. Characteristics are the same. They are structurally intended for winding application in several turns. 
Application of the noise suppression chokes.

Order of calculation

	1. We configure the converter circuit. See typical wiring diagrams.
	2. Choose a constructive version of the choke - single-turn (put on the tap of the diode)
 or multi-turn (mounted on the board).
	The MSB series has been added to the database for the multi-turn chokes. In some cases, several turns on the magnetic core of the MSB series give a good result at small dimensions and price. If the MSB option does not suit you, to select the magnetic core from the MSK series, you must manually click "Next Size" several times.
	3. Set the output voltage and the maximum output current of the load.
	4. Set the pulse fill factor.
	5. Set the time of reverse recovery of the diode.
	6. Set the window fill factor and current density (for multi-turn).
	7. Set the number of the magnetic cores in the package (for single-turn). The default value is 1.
	8. Press the button “Automatic selection of the magnetic core and its calculation”. Program
         will search for the smallest magnetic core and display the calculated data.	
        9. After the automatic selection of the magnetic core (the program selects the core according to the criterion of minimum sizes and prices) and calculation, the user can manually select another core using the buttons "Previous Size" and "Next size", or select a specific core from the list.
	10. In the group “Optimization” (multi-turn), the user has the opportunity to change the number of turns, the diameter of the wire and the number of wires in the winding.
	11. The program includes the size range and characteristics of the domestic PET-155 wire.
For imported wires, there may be significant differences due to the higher resistivity.
	12. The final verification of the project and its refinement are carried out practically in actual scheme. The program can not estimate losses in the core because each particular circuit has its own parasitic parameters of the components and its own shape and frequency of interference.
In some cases, the heating of the core may be excessively large.
In these cases, a larger core should be used.
