3.4.3.1 Setting Software Options for Lab 2

  1. To run this lab, make sure the hardware is set up as outlined in the previous section, Figure 3-9
  2. Open the CCS project as outlined in Section 3.2.1. If using the powerSUITE, go to Step 3, otherwise, jump to Step 4.
  3. Open the SYSCONFIG page and select under the Build Options section:
    • Select Lab 2: Closed Loop CC Single Channel for the Lab
    • Select the Channel
    • Enable the SFRA
    • Open the Compensation Designer TIDA-010090 by clicking the Run Compensation Design button.
    • The compensation designer then launches and prompts the user to select a valid SFRA data file. Import the SFRA data from the run in Lab 1 into the compensation designer to design a two-pole, two-zero compensator. Keep more margins during this iteration of the design to make sure that when the loop is closed, the system is stable.
    • Figure 3-18 shows compensation parameters for the Current Loop.
    • Click on the Save Comp button to save the compensation. Close the Compensation Designer tool.
    • Save the SYSCONFIG page.
  4. When using non-powerSuite version of the project, Build Settings are directly modified in solution_settings.h file. Compensation Designer is found at C2000Ware_DigitalPower_Install_Location\powerSUITE\source\utils.
