5 PSpice model
Figure 23 shows the PSpice model of one DALC208SC6 cell. In this model, the diodes are
defined by the PSpice parameters given in Table 4 .
Note: This simulation model is available only for an ambient temperature of 27 °C. The simulations
done (Figure 24, Figure 25 and Figure 26) show that the PSpice model is close to the
product behavior.
