Hi all
With low dc power means the voltage is 5dcVoltage and 500mA input how out put can produce with the help of inverter. any circuit please help me

You can use a 'Boost Converter' or a Flyback Converter to get Higher Voltages. Topologies for these are easily available on the internet. You can also try a charge pump type circuit too.

But You can not get higher power. If your input power is 5V * 500mA = 2.5W you cannot get power higher than this.
 


Thank you for reply friend. how you caluculated do you hany formula for this. can explain me please
 

DC Power is Voltage times Current.

P = V * I

Using Ohms Law V = I * R

we can also get

P = V2 / R

P = I2 * R

For ANY system you cannot get more energy output than what you have input to the system.
Since Power is the rate of energy transfer, Power output cannot be more than power input.

Since the system will also consume power, Power Output will be always less than Power input.
This brings about the notion of efficiency.

Hope this helps
