Snubber Circuits: Theory , Design and Application
May 93 Snubber Circuits: Theory , Design and ApplicationPhilip C. ToddPassive Snubber TypesThe basic function of a Snubber is to absorbenergy from the reactances in the power fIrst classification of Snubber circuits is wheth-er they absorb energy in controlling a voltage or acurrent. A capacitor placed in parallel with othercircuit elements will control the voltage acrossthose elements. An inductor placed in series withother circuit elements will control the currentthrough those elements. Figure I shows this con-cept. A voltage Snubber (Fig. la) has energy stor-age capacitors in it and a current Snubber (Fig. Ib)has inductors for energy storage. The networksassociated with the inductor and capacitor shown inFigure I determine how energy is passed to thestorage element and how the energy is removedfrom itAll of the otherclassifications of snub-berg relate to the waysin which the energy istransferred to and fromthe Snubber .
