Hello： As shown in the above diagram, it is a flyback power supply for the primary winding feedback control (red line).In addition, there are 3 outputs (green lines) in the secondary.
If loop analysis is performed on this flyback power supply. For example, first analyze the main power Bode diagram, and then design the compensation parameters.
So how should this main power Bode diagram be analyzed? I know the analysis method of single output. If there is no green 3-channel output, then the main power of the orange main power and the red feedback loop constitute the main power.
Now there are three more green output loops. How do I consider the effects of these three output loops on the loop?
The red loop is auxiliary output for IC power supply.
For control-to-output transfer function, It should use the main regulated loop of second side output as the analytical object.
control-to-output transfer function
