I want to design an inverter for a class project, basically I want to power my laptop in the car. My laptop adapter input specs are 120V 60Hz 1.0A. I dont have much experience with transformers so my question is how do i tell which transformer (or if there is other designs I am open to those too) will produce a 120V 60Hz 1A signal?
The DC-AC inverter is the project, im just using the laptop as a desired spec. I could spend $5 and get a DC car adapter fro my laptop, but that wouldnt be much of a project 
.
Why do you need to convert 12 volts DC to 120 volts AC so the laptop adapter can reconvert it back to DC. Why not make a DC to DC converter. Find out what voltage the laptop requires and what current. Then go to Linear Technology's website to see if they could provide technical data sheet so you can use one of their IC's to make your DC to DC converter.
