A block diagram and input parameters for a diode are given in Table 1.

There are two implementations available for the diode: modeled as an ideal switch or as a non-ideal switch (Figure 1 and Figure 2).

If an ideal switch model is used, diode is modeled as a short circuit when conducting and an open circuit when not conducting. In this case, a parallel snubber circuit can be defined. It can be a resistance or a series connection of a resistor and capacitor. These options are shown in Figure 1. Weight of diode modeled as an ideal switch is 1.

When a Use non-ideal switch option is chosen a diode is modeled as a small inductance while conducting and a small capacitances while not-conducting. Weight of diode modeled as an ideal switch is 0. Non-ideal switch models are addressing a different resource called Non-ideal switches.The parameter Resistance (Figure 2) and the simulation step are defining the actual inductance and capacitance values according to the following equations:

$L=Ts\bullet R$

$C= \frac{Ts}{R}$

Where L and C are the calculated inductance and capacitance, Ts is the simulation step of electrical part of the model, R is the set resistance value.
