1.5 Software Setup

  1. To get started, click Cyclone_Project_V01.c item in Project Explorer.
  2. In the srcdab_settings.h file, change the LAB number to select different LAB to run different function as shown in Figure 1-2.
  3. Right click on the project name and click Rebuild Project. Then, click Run → Debug to launch a debugging session.
  4. The project then loads on the device and the CCS debug view becomes active. The code halts at the start of the main routine.
  5. Add the variables in the watch-expressions window. Click on the Continuous Refresh button on the watch window to enable continuous update of values from the controller. The watch window appears as shown in Figure 1-3.
  6. SRCDAB_Direction defines the power flow, 1 represents the charging mode and 0 represents the discharging mode, set the SRCDAB_Direction in CCS watch window before power up.
  7. Lab1 is open loop check, set phase shift angle Phase1_Alpha, Phase2_Beta, Phase2_Fai and frequency SRCDAB_pwmPeriodRef_pu based on power level and input and output range, then set SRCDAB_start to 1, the PWM sends out
  8. Lab2 is close current loop check, the output current can be controlled by setting SRCDAB_iSecRef_pu.
