I need two pwm waves with dead time on PSpice for TI.
To do this I opened the LMG5200 file of TINA where it is already done:



The problem is that I have to use PSpice for TI (for a serious of reasons), so I redesigned the circuit:


In theory, these two PSpice for TI outputs should be the same as those obtained with TINA (i.e., two PWM waves with dead time) .. but they are not.
At the inputs of the AND there are the same signals on both PSpice and TIDA, I have already checked ... so I suppose it is an AND logic port problem.
In TIDA an "if" block is used, in PSpice for TI I used a comparator, making sure the output is the same for both circuits

(I also tried using NAND + NOT but nothing changes).

I have no idea what the issue might be and I don't have much experience with simulators.
What could be the problem?


Thank you all

I think I solved it by re-importing the base library, probably it was corrupted..

 

hi kal.
This is what I get with LTSpice, a very short dead time, which could be the 74HCT limitation.

Hi @kalemaxon89
Out of interest, could you post an image of both the hi/lo switching point dead times, you have achieved using PSpice?
