AC battery , would it be better than DC battery with AC converter

I am thinking of AC battery, where it can directly accept 220V AC and need no converter what so ever to power all AC electric appliances. Your opinion is welcome
 

Re: AC battery , would it be better than DC battery with AC converter

Well it does exist, but isn't called a battery. I don't know the correct english terminology for the unit but directly translated it should be or similar to "rotating phase compensating unit". You may not want to live very close one nearby because it probably sounds like a heavy machine - it is a heavy rotating mass.

To say - it's nothing you got to have used in your regular household, but rather to stabilize voltages at transmission lines.

Alternatively - it is possible to utilize rotating mass more like a battery:

No doubt someone is selling room temperature superconductors on Ebay but I wouldn't recommend buying them :smile:

Batteries work by chemically splitting the molecules into positive and negative charges, one at each terminal. AC batteries do not exist. Also, it is improbable that 220V DC batteries are available (you actually need more to get peak sine voltages). An inverter taking low voltage DC and converting it to high voltage AC is your best option.

Can you be more specific? What are the boilerplate specs (power, voltage, current etc) requirements to power all AC electrical appliances?
 

Re: AC battery , would it be better than DC battery with AC converter

If any battery works with AC input and AC output and any transformer works with DC input and DC output, there will not be a subject called "Power Electronics"

Summary
AC batteries do not exist (for any practical use)

If you have a 220 vac supply there would be no need to charge a battery. You would just run the appliances off the 220 supply like your already doing. Or maybe we're misinterpreting what you are asking.
