Hi! I need some help. I'm confused as to why this selection mode circuit I modified won't work properly with three inputs.

1st input: 0.3 - 0.4V

2nd input: 0.4 - 1.2V

3rd input: 1.2 - 2V

Answer 1

Hi @Danikha Shyken,

I understand that you are trying to analyze why the selection mode circuit isn't functioning properly. As per the specified input ranges the outport signals would evaluate to:

1. Buck Signal: Buck Mode evaluates . This inequality always evaluates to false since max value of (0.4) is less than minimum value of (1.6). Hence Buck Signal is always 0.
2. Boost Signal: Boost evaluates . This inequality always evaluates to false since max value of (1.2) is less than minimum value of (2.4). Hence Boost Signal is always 0.
3. Boost Signal1: Boost1 evaluates . This inequality always evaluates to true since is true. Hence Boost Signal1 is always 10.
4. Stabilized: The AND condition evaluates . From above stated inequalities, we have established that BuckBoost is always true, BuckBoost1 is always true and BuckBoost2 is always false. Hence Stabilized is always 0.

I hope this helps!
