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.

Control Parameters	Default Value	Interval of Variation
DC Source Voltage (V)	100	[0; 400]
Switching Frequency (Hz)	1500	[1500; 3600]
Duty Cycle	0.5	[0.1; 0.9]
Inductance (mH)	100	50 or 100
Capacitance (µF)	400	400 or 800

Table 14: Control Parameters of the Buck Converter

Scope	Content of Scopes & Displayed Waveforms
Scope₁₁	Load output voltage and switching signal (multiplied by a factor of 5)
Scope₂₁	Input current of the DC source and inductor current
Scope₁₂	Load output current
Scope₂₂	Input power of the DC source and load output power
