Hi,
I was trying to design a buck converter as shown in the attached file. When I simulate the converter design in proteus with PWM generated by ATmega32 it is giving a error
"Timestep Too Small"
Can you please try to help me with this.
Attached: Schematic of the converter and the screen shot of the error message.
Thank you. :)

The switching frequency used is 1.96kHz

The timestep is on the order of 1.8 x 10 ^ -19. I suppose the unit is seconds?

This is very slow. I can see it taking weeks to run, and generating a log of results that fills an entire hard disk.

I don't know how to speed up the time step. Can you find a way to set it faster? Maybe around 10 ^ -6 (a millionth of a second). That's several hundred times your frequency of operation.

Yes make as faster as it can be in my case I have changed it to 50p sec when i had encounterd
