high DC voltage and low power

220vdc-220vac power inverter

Hi to all !
I will put this as simple as i can but please give me some suggestions from the "real life" and please be so kind to give answer to all questions becuse it's really importent to me. Thank you in advance !

-------------------------------------------------
Idea:
DC source - 220 V
DC amperage - 100 mA
DC source is something like battery but i dont know if i can look this thru AmperH.
-------------------------------------------------
Goal:
- To power 1KW (AC 220 ~ 50 HZ euro scale ) hair dryer for one hour.
- looking for cheap electronic solution
-------------------------------------------------
Additional options:
- use of microcontrollers
-------------------------------------------------

Questions:
I know this idea is a "bit" abstract but this is just idea.

1.) DC source -- some regulator -- DC\AC converter. --> hair dryer ? This is just idea, please give me your suggestions !

2.) How to organize power needs to reach the goal part

3.) Which hardware solutions can i use to get closer to the goal part

4.) How much AC amperage can i produce with 220 ~ 100mA DC ( with converters, regulators) ?

5.) How much DC voltage and DC amperage do i need (at the source and before conversion) to get 4,54 A at the hair dryer if the DC\AC inverter is on 70% effec. ?

6.) If i can encrease voltage to 500V DC but if the power is still low, can i use some IGBT like two phase converter ?

------------------------------------------------

Calculations for hair dryer option:
t = 1kW/1000W --> 1 hour of work. I = 1000w/220 = 4,54 A

-----------------------------------------------
Please be so kind and give me your suggestions and please give me answer to all questions so i can understand the whole concept.

why run hair dryer on low when on 220

I guess you might have wrong information on your side.

220Vdc seems to me that it should be
220Vac.

You can try using Seal Lead Acid Battery 12Vdc.
Choose a big battery if you want the power to last longer.
A 7Ah or 7 amphere hour batter can run
a device drawing 7A for one hour,
or a device drawing 1A for 7 hours.
A 2A device will run for 3.5 hours.

To power up your AC hair dryer which uses 220Vac,
you can use a device call inverter.
It basically converts the dc voltage back to ac voltage.
Choose a inverter that can manage your ac power consumption.
If your AC device is running 220Vac 100mA,
choose one that can handle at least 2x 100mA.
200mA would be safe.
100mA would be on the margin

No, this is the main problem why im asking this. It is direct curent ( DC ) and all is like i have writed..

Thank you for your time.

Hi,
If I under stand your question correctly? If the source is 220 VDC @ 100ma then you only have 22W to work with. Your converter wont create more power than you put into it. The most you could possible produce in 220 VAC would probably be 90 ma worth of 220VAC if you were lucky.

Can't get more out than you put in. Don't work that way......:|

Good Luck

I understand this but, what i meen is to make some electronics in such way to reduce voltage and to encrease amperage buy using this reduced voltage ( something like charge pump ).

Your converter wont create more power than you put into it.

My goal is to encrease power( amperage ) before i switch to converter.

Please look int question #5 .

Thank you.
