What kind of knowledge i should have for SMPS design

I'm having basis electronic knowledge & i can understand what happening inside of a SMPS, but still i can't start my first own SMPS design. I fear to start my design, its because of the risk of high voltage. Please provide some ideas for beginners...
Where i can start for learning, from transformer or electronics circuit? I believe electronics circuit is not a big issue where we can get sample circuit, forum help, datasheet, application diagram, etc., (or it may be my thought, because i can understand electronics more easier then magnetic circuit). How do i gain knowledge in SMPS transformer design? Lot of application notes & study materials are available in internet which is not possible to study everything.
Which one is a best (way or) study material for a beginner to start SMPS design, because I'm really in need of own SMPS design...

Lots of information here.

Start out with low voltage smps, like 12 volt dc push pull to 24 or 36vdc.

Books and diagrams are fine...

But an animated video is extremely helpful for gaining insight.

I have a Youtube video which shows basic principles of buck/ boost/ buckboost converters. It depicts current moving through wires, flux fields building and collapsing, capacitors charging and discharging.

My posts contain links which open my animated interactive simulations of switched-coil converters. (Drawn in Falstad's animated simulator.)

You press a switch to close it, sending current through the coil (the first half of the cycle).

You let up the switch to open it (the second half of the cycle).
