www.st.comII.2 The “Boost” converter: Step up voltage regulator Figure 2 : The step up “Boost” regulator In normal operation, the energy is fed from the inductor to the load, and then stored in the output capacitor. For this reason, the output capacitor is stressed a lot more than in the Buck converter. V in 1-δ V out = ton T δ= Device ...

www.ti.comBoost and input filter inductors and single winding flyback inductors are often designed to operate in the continuous mode. As with the buck-derived filter inductors described previously, inductor design is then usually limited by dc winding losses and core saturation. However, many boost and flyback applications

An inductor in series with the switch, a comnt snubber, presents the switch with an inductive load at turn-on so that it switches on with zero comnt. This is a modifi-cation of the load which would typically be some-what capacitive at turn-on.
