Greetings,
Having had 2 car power inverters die on me after only a few uses (12V --> 240V, one 300W and the other 150W), I was reading about how fickle these things actually are.
A couple of things I was wondering: first about the technology itself. I opened the 300W to see if I could find a blown fuse or something. There were 2 but both intact. What I did notice was the amazingly complex circuitry for something with such a simple function: a surface mount board more packed with ICs and other components than my PC's motherboard - in addition to the expected large transformers, capacitors, power transistors etc, also a peripheral board mounted at a right angle as crazy as the main one - just insane. Surely there cant have been any need for all that!
The other thing: Although I'm tempted to build one myself without all that bloated, easily damaged crap, I still have my rule about not messing with mains power, BUT given the kind of stuff I wanted the inverter for in the first place i.e. phone and laptop chargers and basically devices that operate in the 5-12V region via a transofmer, why not skip that whole step. I assume that all I would need is some basic current protection and a voltage regulator right? (and maybe a voltage doubler for the occasional device needing 24V)
