CCS/TMS320F280049C: DeadBand_Swap and DutyPU issues in TIDM-1007

Part Number: TMS320F280049C


Tool/software: Code Composer Studio

Dear Sir,

1. In pfc1ph3ilttpl.h, from line no.833 to 835 (positive ac cycle) and line no.851 to 853 (negative ac cycle), why DISABLE_SWAP_DEADBAND is required for positive ac cycle, and ENABLE_SWAP_DEADBAND is required for ac cycle?

2. DutyPU represents the duty cycle, and in the program of this project, we found that the values ​​are 0.004, 0.01, 0.1, 0.5, etc.; May I know, how many percentages does each of the above values ​​represent? That is, 0.004=0.4%, 0.5 =5%, right?

3. what is the difference between DutyPU and DutyPU_DC ?

 

Best Regards
