What I do to get 230 V AC output instead of 110 in following circuit:`?

Answer 1

You need to use a transformer

Answer 2

Change the T1 transformer. Instead of a 24/110 you would use a 24/230. You could also buy an adapter to plug into the original cicuit that would step up from 110v to 230.

Answer 3

You have to use a different transformer. Instead of a 110v to 24v CT transformer use a 220v to 24v CT transformer. Theoretically you can also use a 110v to 12v CT transformer, if the 110 winding will withstand double the voltage (it probably can).

EDIT: In answer to marianna, the primary voltage supply remains at 12V. The asker did not indicate taking any more power from the inverter, only higher voltage (which means less current at the output, for the same power). The primary circuit is not affected.

Answer 4

While I agree with above answers in principle, no-one talks about the key component, the 2N3055 x 2.
Changing the primary side of the transformer from 24V to 12V doubles the current through the transistors. Will they survive that?
I am anyway surprised that the Web Page you refer to did not mention anything about mounting the 2 transistors onto substantial heat sinks! You will have to.....

Answer 5

A 120/240 - 12/24 V 1KVA transformer should be readily available. Wire the 120.240 side in series to get 230v, and in parallel to get 115V.

Answer 6

i don't want to be nasty, merely frank yet this present day you may't detect a working laptop or pc somebody is throwing out with usb ports you should use to value in spite of it is your utilising? the only different difficulty may be in a automobile and you will purchase a techniques safer designed cigarette lighter adapters than attempting to construct one for relating to an identical value. we've an previous junk equipment in the returned of our workshop somebody exchange into going to throw out that has 3 makes use of, charging our MP3 gamers, enjoying the 2d participant of a few networked video games after paintings hours and checking our emails.
