Operation of the DC-DC Converter in Battery Charging Mode - Case A
Understanding the Panel
Figure 9 shows the primary Dashboards panel of the laboratory related to battery charging mode. This panel enables the user to manipulate the entire circuit, retrieve desired values, and observe plotted signals. Initially, all switches are turned off.
Figure 9: Case A- Main Dashboards panel.
The panel is to be operated as follows.
At the top, there are control parameters and switches for the simulated circuit. The user can modify circuit parameter values and change switch statuses according to the laboratory task. These parameters and switches are summarized in Table 2.
Parameters/Switches | Initial value/Status |
|---|---|
Switching Frequency (Hz) | 22000 |
Duty Cycle | 0.612 |
Battery Voltage (V) | 400 |
Open/Closed loop | Off |
