How to solve the problem of capacitor flattening
Use output capacitor(s) with lower impedance at the switching frequency. This will be the focus of the discussion here. Paralleling output capacitors is an effective way to achieve this. Here is an example of LF ripple reduction by using two parallel capacitors instead of one: Also, you can choose a different capacitor type altogether. - Download [PDF]

How do switch mode power supplies solve the half energy loss problem …
If we charge a capacitor C with a DC source of voltage V, the energy stored in the capacitor is ½CV² and the energy wasted in wires is also ½CV². Many videos say that SMPS minimizes this cleverly by switching fast and thus not allowing the capacitor to fully discharge. I don''t get how the energy is not wasted in fast switching.
