HI,

There is a problem during simulation there is no gate pulse from IC.

also I add the tina-ti file.

Please find below attachment.LLC RESONANT.TSC

Hi Nilakantha,

FYI, we're looking into this.

Hi Nilakantha,

Thanks for sharing the .TSC file. We have looked into it. Below are the changes we made to make it work.

1. Made the Ground connection properly at the input stage.

2. Connected the outputs OUTA & OUTB properly.

3. Added diodes D1 & D3, resistors R5 & R29 to help simulation convergence.

4. Corrected the value of resistor R24 (changed from 2.37Ohm to 2.37kOhm).

5. Changed the following analysis parameters

TR max. iteration number: Changed from 20 to 400

TR max. time step (sec): changed from 10G to 20n

PFA the updated project 0636.LLC RESONANT.TSC.

Below is the updated simulation result.

Thanks & Regards,

Arpan Gupta
