I use MTRDEVKSBNK144 Application Software.
I have a question about the application code.
1. For sensing the DC link voltage, DC link current, Phase voltage,
PDB_DRV_SetTimerModulusValue (INST_PDLY0, HALF_PWM_MODULO);
Is there any reason to set 2000 to 4000 instead of Full PWM?
When setting to HALF_PWM, I want to know if AD conversion is possible for 0 ~ 2000 and AD conversion is not possible for 2000 ~ 4000.
2. For sensing DC link current, It sets PDB delay to 0 for sensing in PWM center,
For sensing each phase voltage and DC link voltage, I know that the PDB delay varies depending on the output duty cycle value.
At present, the value information of other sensors is required, so it is necessary to add about 4 channels.
Therefore, the PDB delay must be add in AD sequence.
I want to know the minimum PDB delay time for other AD conversions after one AD conversion in PDB_DRV_SetAdcPreTriggerDelayValue().
3. Is there any other way not to add PDB delays?
For example, a continuous ADC
