Buck Converter Design and Feedback Controller Using Core …

WebIf you put a sufficiently good oscilloscope on a buck or boost converter, you will find that it is NOT DC, it is just approximately DC. In reality, it is DC plus a slight ripple; this ripple will have a frequency that fits with the characteristics of the LC filter you have built into your circuit. \$\endgroup\$ – WebMay 5, 2024 · Here is the issue. From an ideal buck converter with no input filter, the inductor ripple current is ((Vg - V) * D * Ts) / (2 * L). This should be the same for L2 in the above circuit. If VC1 = Vg then I would calculate the inductor ripple in L2 as: Eq. 1 : ((Vg - V) * D * Ts) / (2 * L2) It's the same as before!
