Hello guys. I am a final year student doing a project on buck-boost converter with input of 9V-22V to produce output of 12V. My circuit needs to include power switching device and pwm. Any idea how can I construct my circuit on proteus to simulate? Thank you.
You can't get what you want with one converter. There are 2 options; 1. With step up converter convert the input to say 30V and then a step down converter to 12V. 2. Step down converter to 5V and then step up to to 12V.
Option 1 is likely to be more efficient.
