AC-to-DC Rectifier LAB3 - Panel

When starting the demo, the panel in figure 21 appears first with the default settings.



Figure 21: Start-Up Panel of the Three-Phase Thyristor Bridge Rectifier Laboratory

For operation of the three-phase thyristor bridge rectifier panel, the student can refer to the panel operation of the single-phase diode bridge rectifier, because the panels of both models are very similar.
The differences in content of scopes, control parameters and buttons, and contents of displays are presented in tables 16 to 19.

Associated Functions

Trigger

The waveforms are not triggered. They “move”.

The waveforms are triggered with respect to a reference signal.

Data Acq.

Data acquisition is disabled.

Data acquisition is enabled and allows to record .mat files for offline studies, in particular harmonic analysis.

Fuse

 

 

The protection fuse is blown.

The protection fuse is intact.

HELP/BACK

Open the Help page, where a summary of three-phase thyristor bridge rectifier is shown.

Close the Help page and go back to the simulations.

Switch

 

AC Source frequency, 50 or 60 Hz.
