low5545 WROTE:I want to convert DC voltage from a battery to AC voltage through an inverter circuit below
This circuit is quite simple and straight forward. The transformer is also easy to get. But at your age, isn't it better to play with something safer till you gain more experience? The secondary of the transformer will give you 240V a/c and if not careful, could give you a big shock and might kill you!!
I agreed with Brian that this experiment should be tried with supervision if you really want to try it out. It'd be OK if you just want to discuss about the circuit. Actually I quite admire you that you started to get interested in Electronics at such an early age. At your age, I was still playing guitar and watching my dad changing the fuse when one of the lights get burnt.
