I am sophomore doing a project on Auto Voltage Selector. My project works such that depending on what voltage the load requires (110 or 240), the supply automatically switches to the required voltage.
I do this by using 2 different comparators that takes and only one of them is on at a time which triggers one of the triacs at a time.
I got info and help for this project from this website below.
**broken link removed**
The problem is that I couldnt find the lat part required for the project that is the switching transformer and I don't have the time to wait for it.
My colleagues suggest we use a switch ckt instead for the demo purposes whereby one switch wuld trigger 110 volt and other switch wuld trigger 220 volt.
I understand that voltages in series add up and I used that technique to make the switching ckt but end up getting the same 110 volt at the finla output.
This is the scenario
A-----(Live Wire from Primary Winding)
B-----(One of the selectors)
C-----(The Second Selector)
I am getting 110 V between A - B and 110 V between A-C. So since they share the common node, when I connect them in series, I dont get the 220 V I need.
Any advises on how I can complete the project.
