hi mo,
You have the pulse model I posted #9, use the method described by papa in post #23, to inject that pulse.

Do you know how to do that.?

Also, we need the lib.txt file for the component parameters.

actually i am still not sure how to do it as i did not understood fully. The problem with me is that i am new in LTSpice and i am not fully aware with how to use different functional blocks in LTspice.

 

hi mo,
That lib file includes unused models, modified to lib2.txt
You can try these two idea's.
What does your circuit represent.?

Hi eric,
its for an inverter driving a motor.
The issue with your pulse is that the duration of transient should me 10ms but the pulse you generated, its 20ms. I tried to reduce it but then the overshoot goes beyond 1100V. Can you pls assist how to fix that?
Thanks

 

hi mo,
Are you measuring the pulse duration from the 10% levels of the pulse.?

hi mo,
Check this old and new pulse.

Use Alternate in Tools Menu

Improved match.

Hi Eric,
I am talking about this interval. Pls see attached screenshot. I want to make this interval 10msec instead of 20msec

 

hi mo,
The BLUE plot in post #30 pulse width is 10mSec.
Unless I misunderstand what you are saying.?

Hi Eric,
The pulse is ok now.
Thank you so much for your assistance and support
