Hello. I want to design a transformer that steps up the Vp=48VDC to Vs=330VDC. I am using ETD59 3C90 ferrite core and the switching frequency is 100KHz. I want to build the h bridge configuration for the dc-dc converter. Hence, the maximum duty cycle that I can have is 45%. So, this nominal voltage needs to be at 30% duty cycle so that after the feedback, if the output voltage exceeds 330VDC I will decrease the duty cycle from a range of 0 to 30% and if the output voltage falls short of 330VDC, I will increase the duty cycle from a range of 30% to 45% accordingly. I want to calculate the accurate values of turns ratio relating to this max duty cycle accordingly.
