Also seems like I do need help with implementing these IR2117 gate drivers to work. This seems like an easy task since the application circuit is in the datasheet and I am familiar with the concept of high side gate drivers but I cannot run the simulation at all right now and my other attempts with this or other drivers failed.
View attachment 205955I did however manage to drive mosfets with HCPL-3140 optocouplers but this solution seems to be too slow for my application.

Also please find attached asc files that you might find useful in case you could help me.
- behavioral_sources.asc is for the 1st post in this thread, the mosfets are drived by voltage sources that are identical to PWM output of the control loop,
- gate_drivers.asc is for this post

Thank you for your time!
Hey,
Hope you are doing well. Even i have the assignment of this and i have been trying to understand the concept since I am new to this. When i was searching i found this article which really grabbed my interest. I really need help on simulating LLC converter in LTspice. If u could help me with this, it means a world to me. I attach my email address please drop me an email. Thank you and have a nice day
