Would a square waveform (or trapezoidal waveform) have frequency content lower than its fundamental frequency?
I was trying to understand the LC circuit response for the circuit given below.
(Note: fsw indicates the frequency of input square wave as in a buck converter)
As far as I know, for a linear circuit, ...

Transient time in buck converter
To my understanding the reactive components in a converter should not store energy over a switching period, otherwise they will blow up. An in inductor for example abides by volt-second balance, which ...

Approximation when deriving buck closed loop transfer function
Can anyone explain why \$\frac{\Delta V_x}{\Delta D} = V_{in}\$ here? It seems to me that they are assuming that \$V_x = V_o\$ ( this is only correct for average voltage). However, if they use the ...
