Hi engineer,
We use LM5017 to design a fly buck circuit.The document SNVA674C shows the basic operating principle of the fly buck circuit.There are a few questions,please help us to confirm it.
1:In figure1,is IL1 refered to current in the primary winding and IL2 refered the current to the secondary winding? and which waveform is the IL1?
:
Figure 1
2:What is the magnetizing currrent reffered to? And what is the differences between the magnetizing current and the IL1 in the figure 2 ?
Figure 2
3:In figure 3,why is IL1 equal to Iout1 on a cycle-by-cycle average basis?
Figure 3
4:In figure 4,is ΔIL1 equal to 0?
