I am shashank from India. I actually wanted to build a circuit which can step up 12V or 24V to around 230V. The current rating of my batteries would be around 10-15Ah. Since my application is a battery operated vehicle, i cant opt for a transformer as such. The circuit should be able to step up the voltage, amplify the current and that too with a good efficiency. Would you please suggest me such a circuit using power electronics anything of such kind?
How many such batteries would u suggest me to connct in series? because that even adds a lot to the weight and hence in the reduction of the BHP of the motor!
I would suggest you do alot of googling on the subject of electric cars. They are certinly not simple.
If you are trying to make an existing car into an electric car, che out some of the kits made. Google for "electric car conversion" or somthing like that. It will give you an idea of all the stuff that is involved.
