3.1.2.3.2.2 Designing the Current Loop Compensator

1. Click the compensation designer icon from the powerSUITE page to launch the compensation designer.
2. The plant model for the inverter for the output current loop is created using the parameters specified on the powerSUITE page.
3. The compensation designer GUI enables editing the lead lag compensator, which is also a part of Gi
4. If a change is required to resonant and PI controller, close the compensation designer and edit the values on the powerSUITE page.
5. Save the page.
6. Relaunch the GUI.
7. Verify the stability of the system by observing the gain and phase margins on the open loop transfer function plot in the compensation designer, as shown in Figure 28.

8. Once satisfied with the compensation design, click Save COMP.
9. Save the compensator values into the project (for example, when the project is recompiled, it will use the new coefficients for the compensator).

NOTE

If the project is not selected from the solution adapter, the compensator cannot be changed. For a unique design, select the solution through the solution adapter.

10. Close the compensation designer and return to the powerSUITE page.
