is your source a variable input?? does the output need to be linear?? it says the maximum output current is 1A i think this suggests that 1A @ a low Vin is also the maximum input current. therfore 1A in @ low Vin will give 1A out Maximum.
I suppose you could opt for a higher output voltage then drop the voltage accross a resistor network to boost the current to your required rating. However this will not work for a variable input. if the input is variable does the output current have to be fixed??
OK i understnad - no variable input you just want to know the relationship between the currnet and voltage in an inverter.
basically it is the same as with any conversion. The power is always the same. for instance if you are converting from 24VDC to 12VDC you are halfing the Voltage so the Current is doubled.
So 24VDC to 6VDC is a division of 4 so the output current is 4 times the input current.
They're neat, but notice that there is a small conversion power loss involved, somewhere between 5-25%, depending on the specific inverter and its operating conditions.
