Hello
I am trying to simulate a buck converter in Proteus which is required to convert 17V to 12V approx. Based on the simulation circuit, I will be implementing the hardware. I used a schematic which I found in one of the threads here.
Keeping the Pulse width of the PWM signal at about 5% I'm able to obtain about 12V output but the current is too low. Considering that I need to supply to a battery for charging it,a decent level of current is needed which I'm not able to get.
Plus if I connect a load of no matter how many ohms, the output gets reduced considerably.
Any help would be much appreciated.
Thank you
