I am relatively new in the field of Switch Mode Power Supplies but I was looking at the Flyback converter with an input voltage of between 30V to 88V DC and an output that would charge a 24V lead acid battery bank. The main reason for deciding on this topology was the power requirements of 720W.
The best transformer that I could find off the shelf is a 250 Watt Wurth Elektronik with part number 760895741 that is designed for 220Vac mains use where the input voltage to the transformer is between 320Vdc and 350Vdc. It has a turns ratio of 27:3:3:2.
My question is this: if I change the input frequency, will this effect the output voltage as higher frequencies in SMPS results in smaller inductors?
