WebFeb 20, 2024 · A buck-boost converter is a switch-mode DC-DC converter that provides an output voltage greater than or less than the input voltage. The arrangement of a buck-boost converter circuit is similar to that of the buck converter and boost converter circuits; in fact, it is a combination of both these circuits. WebDec 12, 2024 · Unlike with a buck converter, the duty cycle is a tradeoff between enough time to store energy in the inductor, and enough time to deliver the stored energy to the load. 100% duty cycle, for example, continuously charges up the inductor but never delivers anything to the output.

WebThe key principle that drives the boost converter is the tendency of an inductor to resist changes in current by either increasing or decreasing the energy stored in the inductor magnetic field.
