I'm trying to construct an SMPS power supply with 230VAC at 50 Hz input and 5.6V/2.5A output. Here is the schematic:
The design was optimized with EE19 core selected and I am expected to optimize the power supply with EE16 core to save space on board. The problem is that, as PI expert simulation indicates, maximum flux density limit exceeded.
1) What points should I take into account to solve this problem?
2) Is there any recommended book, or resource to understand the theory better?
I've just worked on PS unit; so, I really appreciate any comments whether it is related to my problem, or not.
