LAB 2 - Panel

When starting the demo, the panel in figure 13 below appears first with the default settings.

Figure 13: Start-Up Panel of Buck Converter Laboratory

For operation of the buck converter panel, the student can refer to the panel operation of the boost converter, because the panels of both models are very similar.
The differences in control parameters, content of scopes, and nameplate ratings for the buck converter are presented in tables 14 to 16 below.
