The buck–boost converter is a type of DC-to-DC converter that has an output voltage magnitude that is either greater than or less than the input voltage magnitude. It is equivalent to a flyback converter using a single inductor instead of a transformer. [1] Two different topologies are called buck–boost converter. Both of them can produce a ...
A buck converter or step-down converter is a DC-to-DC converter which decreases voltage, while increasing current, from its input to its output . It is a class of switched-mode power supply . Switching converters (such as buck converters) provide much greater power efficiency as DC-to-DC converters than linear regulators , which are simpler ...
The Ćuk converter [1] (Serbo-Croatian:, English: / ˈ tʃ uː k /) is a type of buck-boost converter with low ripple current. [2] A Ćuk converter can be seen as a combination of boost converter and buck converter , having one switching device and a mutual capacitor, to couple the energy.
Fig. 1: Schematic of a flyback converter. The flyback converter is used in both AC/DC, and DC/DC conversion with galvanic isolation between the input and any outputs. The flyback converter is a buck-boost converter with the inductor split to form a transformer, so that the voltage ratios are multiplied with an additional advantage of isolation.
Typical multi-tap buck–boost transformer. A buck–boost transformer is a type of transformer used to make adjustments to the voltage applied to alternating current equipment. [1] Buck–boost connections are used in several places such as uninterruptible power supply (UPS) units for computers and in the tanning bed industry.
A boost converter or step-up converter is a DC-to-DC converter that increases voltage, while decreasing current, from its input to its output . It is a class of switched-mode power supply (SMPS) containing at least two semiconductors, a diode and a transistor , and at least one energy storage element: a capacitor , inductor , or the two in ...

The boost/buck capabilities of the SEPIC are possible because of capacitor C1 and inductor L2. Inductor L1 and switch S1 create a standard boost converter , which generates a voltage ( V S1 ) that is higher than V IN , whose magnitude is determined by the duty cycle of the switch S1.
