Smps disable output protection5/26/2023 ![]() When the switch is closed, in steady-state the voltage across the inductor, v L, is zero, and a dc current I 0 flows through the inductor. Switching in an Unprotected Inductive CircuitĬonsider the circuit shown in Figure 1(a). Part II (to appear in the March 2019 issue of In Compliance) will address the systematic process of the snubber circuit design, together with the simulation and verification through the laboratory measurements. The impact of an RC snubber on the circuit performance is demonstrated through a series of simulations. In Part I we discuss the fundamentals of the inductive switching and the need for circuit protection. T his is the first of the two articles devoted to the topic of an RC snubber design.
