Is the LC filter rectified on the secondary side of the power supply high-pass or low-pass?

What power supply are you? What type of output?

Conventional flyback, the output is DC, what is DC?'Infinite low frequency'. LC is low pass at this time.

Can you analyze the others yourself?

Let's first see what is the definition of low pass and high pass.

Then you write the transfer function after LC filtering, you will know what type of filter it is...

The power output is generally DC, of course it is low pass...
