Im looking into building a small inverter as an add-on for my project. I need to be able to heat a 100w heat bulb from a 12v battery.
If iv done my sums right then thats a current draw of about 0.5A on the hot side, on the cold side i will be pulling about 8A @12v.
Iv been looking for a fairly basic inverter circuit for a few days now, but in order to do this im looking at needing a 8A+ transformer. Currently i have a 9-0-9, 4A transformer and thats big enough as it is.
Would anyone have handy a decent schematic of a smps type inverter, i know they generally use a TL949 chip, but when looking on the net for these type inverters i always get one that needs a huge transformer.
I know its probably easier to buy an inverter and add it in but in the long run i hope that my overall project will get to market, so would like it all on 1 board.
Any help would be great.
