Other Parts Discussed in Thread: TIDM-1000, CONTROLSUITE

Tool/software: Code Composer Studio

Dear Sir,

When I am working with the example TI Designs: TIDM-1000, I am not getting the PWM Gate pulse like above shown in pdf file. I got the overlap pulse for Q1 and Q2 like below.

The ti example default path in controlSuit is C:\ti\controlSUITE\development_kits\tidm_1000\v1_01_00_00

Ajeet,

Yes the PWM are configured to be overlapping,

By not switching one of the PWM, one can save some switching losses, however, if you do have current bi-directional devices you can use the overlapping pulse to save on diode losses.

I'll note this down as a clarification to be made in the documentation.

regards

Thanks to you Bhardwaj Ji

Current bi-directional devices means RB-IGBT shown in figure

Thanks for your support
