I could not find this question on this forum and want to have few opinions in this regard.
I want to choose a transformer for boosting around 10V to 30V in a Flyback converter configuration and later form +15V/ -15V. This transformer is used to generate voltage which is used to drive electronic components like OpAmps, Mosfets etc. The Power Rating will be around 3W.
My question is : What will be the difference if I take the Transformer Configuration A with only one Primary Winding and one Secondary Winding or if I take the Transformer Configuration B with connections shown having one Primary Winding and two Secondary Windings joined together as one.
Will there be any difference between both Transformers regarding EMI performance if same Primary to seconadry Turn Ratios and Power Ratings are taken ? Which configuration has better performance regarding EMI and voltage stability over the other ?
Thanks alot for sharing your experiences.
