        1. The cores are made with ready-gaps.
A number of ready-made gaps can be found in the manufacturer's documentation (datasheet).
The gap should be selected from a standard range of values for the core.
If it is impossible to purchase the core with the desired finished gap, it is possible to make a gap with spacers.

        2. The program specifies the full value of the gap.
The gap made with the thickness of the gasket will have approximately half the required gap size. The effective length of the gap is shorter than the geometric length of the gap of the magnetic field due to bulging in the gap.
Therefore, it is desirable to choose thickness of spacers on the meter inductance until the calculated value of the primary inductance is available.

        3. The reflected voltage is the voltage that is "reflected" by the secondary winding through feedback when the energy from the transformer is being dumped into the buffer capacitor.
The reflected voltage is calculated with the output voltage and the transformation coefficient like with a normal transformator.

        4. Typical current density for natural convection is between 4-6A/mm^2 and 8-10A/mm^2, (depending on air flow) if a fan is used.

        5. The continuity of the current means that during the energy transfer from the feedback not all energy that is in the core is being transferred.
Part of the current remains in the induction, and if the switch is opened, this unused current starts to flow.
0% means a discontinuous current. The continuity shows what part of the current remains unused.
		
        6. I suggest to let the program calculate the diameters of the wires and the number of the wires in the windings first to make the best of a given diameter.

        7. To calculate the clamper there are 2 methods. The options are a direct calculation of capacity for a given voltage spike on the switch and a reverse calculation of the voltage spike on the switch with a given capacity. The method used depends on the position of the switch.

        8. With the reverse calculation of the voltage spike on the switch from a given capacity of the clamper, it is possible to evaluate the leakage inductance of the transformer and the equivalent capacitance of the circuit.
The equivalent capacitance of the circuit includes the installation capacity, the output capacitance of the switch, and the capacity of the primary winding of the transformer.
For this calculation it is required to identify two periods of free oscillations with an oscilloscope.
To determine the period of free oscillation of the primary inductance, the measurements should not be taken at full load, so that after the energy transfer from the transformer, a sufficient number of free oscillations could be observed during the measurement period.
The measurement of the free oscillations of the leakage inductance is best done with a maximum load, when the oscillations have the greatest intensity. But it may be sufficient to assess these oscillations in the measurement period for the waveform, which will be measured by the period of oscillation of the primary inductance.

        9. To add a new core to the database, you have to enter a name.
There is no need to manually add a prefix about it's form, the program adds it automatically.

	10. When adding a new core to the database, it is better to use the checkbox "Add to database (input data)". Please take the parameters from the manufacturer's documentation.
     The symbols mean the parameters:
	Ae - Effective cross section area, mm2
	An - Area of the core window, mm2
	le - Length of the magnetic path, mm
	Ve - Volume of the core, cm3
    In case the manufacturer's documentation misses the window area of the bobbin for the winding, calculate the area of the window yourself.
    The volume of the core is calculated by the program. Core volume is the product of cross-sectional area of the core and the length of the average magnetic line.

	11. If "Other" is chosen as the form of the core, please take the parameters from the manufacturer's documentation.
