i have a dc to dc converter of 48V input and 24 volt output giving 20 Amp maximum output current , now how can i calculate the current input or drawn by the converter?
dc ot dc converter
- Thread starter sujinvipin
- Start date
Shall i confirm with it or is there any better solution
What is the problem? Is that too complicated?
If you don't know the converter efficiency, you will need to calculate it by:
Efficiency = PowerOutput / PowerInput
You already know the output power requirement, correct? 24v * 20A = 480 Watts.
You already know the input voltage, correct? 48V, right?
So, you need to at least find out one of the two missing variables; input current, or converter efficiency.
If you don't know what the converter efficiency is, then guess low. Estimate 75% to 80%.
