What more detail do you need? I would like to know the recommended deadtime for the TMDXIDDK379D development motor controller from TI.

You can refer the code released in MCSDK for this settings. Once installed, you can import the reference code in ccs: in C:\ti\c2000\C2000Ware_MotorControl_SDK_5_02_00_00\solutions

I see its 200 ticks/counts as per the refernece code:

Hi Sumit,

I cannot find this file. The 200 counts is not enough information to calculate the deadtime. Can you tell me the SYSCLK frequency and PWM clock dividers (HSPCLKDIV and CLKDIV) that was used?

Thanks

Bobby

Its EPWMCLK is 100MHz so this is 200/100MHz = 2micro-seconds.
