Hello all,
I would like to know the significance of putting a load resistor at the output side while designing a DC-DC Converter....For example, i am designing a 3KW DC-DC converter(assuming 400V 7.5A at output)....Then i put a 62.2 ohm resistor at output and measured voltage across it and getting around 400V DC...If i am using the same converter for some application whether I need to supply that 400V across the resistor to the load or I need to replace the resistor and connect the actual load instead?.... If so, does there exist such a 3KW rated resistance other than a huge rheostat?
I know these are the very basic level doubts that may be due to an improper understanding of the basic principles...But I love to build the fundamentals through forums !!!
