LAB 1 - Panel

When starting the demo, the panel in figure 5 appears first with the default settings.

Figure 5: Start-Up Panel of Boost Converter Laboratory

The panel is to be operated as follows:

  • In the upper right corner, under Pre-Selected the student can select the type of load, which is either resistive or inductive.
  • Once load type is selected, the student can select the load value. For a resistive load, the scenarios are shown in figure 6; while figure 7 presents the inductive load scenarios.

Figure 7: Changing the Inductive Load Value

  • In the lower left corner, the student can change control parameters and can switch control buttons (to enable/disable their associated functions). Table 1 summarizes the control parameters, while Table 2 is dedicated to the control buttons.
  • After setting the control parameters, the students can observe the waveforms displayed in four scopes. More details about the displayed waveforms are given in Table 3.

Control Buttons

Associated Functions


The waveforms are not triggered. They “move”.

The waveforms are triggered with respect to a reference signal.


The reset push button is disabled.

The reset push button is activated and simulates replacement of fuses after a fault.


Open the Help page, where a summary of the boost converter and its nameplate ratings (see Table 4) are shown.

Close the Help page and go back to the simulations.


Red: The protection fuse is blown.

Green: The protection fuse is intact.

On scope localization, the indices used will be like those of matrix elements.
Hence, the scope located in the upper left corner (first row, first column) is denoted Scope11, while the scope in the upper right corner (first row, second column) is Scope12.
By the same token, the scope in the lower left corner is Scope21 while the scope in the lower right corner is Scope22.

The knobs “y-axis offset” and “y-scale/div” can be used to modify the range settings in the y-axis for the scopes.
