I am making a science fair project in which I'll need to pump water through a small distance. I am using a small submersible aquarium pump (5W) for this purpose. I don't want to meddle with 230V mains since water is involved.
Can anyone give me any ideas for making a low power inverter for this purpose?
Will the pump need a modified sine wave or will it work on a square wave?
I am thinking of using a H bridge made out of TIPS/3055s driven by a 555 to produce 60Hz 12V AC which will be stepped up by a 12-0 transformer.
Will it work?
I want to keep this as simple as possible and don't want to go for readily available circuits from circuits.com ect as i will understand nothing by building them.
Efficiency doesn't matter. I would be happy if it runs for 15 mins when it is powered by a 12V 8 AH battery.
