Hi
Regarding to EVAL_3K3W_TP_SIC
I'm trying to change the dead time thru below GUI.
the prolem are:
1) I have no idea what is the actual time (ns) of count unit in GUI, for example MAX 12 counts CLK what is the actaual time?
2) For reg1_limit 4,172 counts of current ADC , What is the actual current (A)?
3) Current ADC in GUI mean output current, right?
4) Diode_to_Switch, what dowws it mean?
Solved! Go to Solution.

Hello,
Good Day!
Thanks for posting your question in Infineon Community.
- I have no idea what is the actual time (ns) of count unit in GUI, for example MAX 12 counts CLK what is the actaual time?
Dead-time is introduced using Infineon SMPS GUI. Dead-time parameters update via UART communication. Each step for calculating dead time is calculated based on clock frequency. The clock frequency is 96MHz. Please refer control_interrupts.h file in the Dave project.
- For reg1_limit 4,172 counts of current ADC , What is the actual current (A)?
Actual current = 7A
- Current ADC in GUI mean output current, right?
No, it's inductor current Input side
- Diode_to_Switch, what dowws it mean?
Please refer to EVAL_3K3W_TP_PFC_SiC_GUIintro.docx document for a better understanding of Diode to Switch and Switch to Diode transition in section "2.1 Current dependent dead time concept"

Thanks a lot !!! Vinay
By the way , I can't find the excel file "PFC_3K3_totempole_DTcalc_GUI..xlsx for parameter calculation.
Pls help to share
Thanks
