Other Parts Discussed in Thread: TINA-TI

Hi everyone,

As I am new in using TINA-TI software, I met a simulation problem on TINA-TI software.

From the picture below, the d-s voltage waveform of the power mosfet is not a 355V-0V 100kHz square waveform.

So want someone to help to look at the attached .tsc file to see where the problem is.

Thank You very much.
