Energy Characteristic Default Row Description

• The nom row is the measured data under the nominal working condition. This data provides the basis for the energy correction of other working conditions, and is required for the calculation of the correction coefficients. The Enable check box for this row is always selected. The nominal working conditions are populated to the second to tenth rows of data according the pre-defined format.
• The dT row is data at a different temperature T_j from the nominal value. This data is used to calculate the temperature correction coefficient. In this row, only the value of T_j and the switching energies are editable. The rest of the data is copied from the first row. If this set of data is not available, clear the Enable check box and the temperature correction coefficient will remain at its default value.
• The nV and pV rows are data at a different collector-emitter voltage V_ce: one at a higher voltage than the nominal V_ce and the other at a lower value. This data calculates coefficients for doubled-sided voltage correction function (see the IGBT Average model reference in the Twin Builder Components help for more information). In these rows, only the value of V_ce and the switching energies are editable. The rest of the data is copied from the first row. If this set of data is not available, clear the Enable check box and the voltage correction coefficient will remain at its default value.
• The nI and pI rows are data at different collector current I_c: one at a higher current than the nominal I_c and the other at a lower value. This data calculates the coefficients for doubled-sided current correction function (see the IGBT Average model reference in the component help for more information). In these two rows, only the value of I_c and the switching energies are editable. The rest of the data is copied from the 1st row. If any of these sets of data is not available, clear the Enable check box and the corresponding current correction coefficients will remain at its default value.
• The nRgon, pRgon, nRgoff, and pRgoff rows are data at different gate resistances: at a higher and lower On-Switch resistance or at a higher and lower Off-Switch resistance than the nominal R_{g_on} or R_{g_off} and the other at a lower value. This data calculates the coefficients for doubled-sided gate resistance correction function (see the IGBT Average model reference in the component help for more information). Only the value of R_{g_on} orR_{g_off} and the switching energies are editable. The rest of the data is copied from the first row. If any of these sets of data is not available, clear the Enable check box and the corresponding gate resistance correction coefficients will remain at its default value.
