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 ...
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 ...
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.
The two operating states of a buck-boost converter. When the switch is turned-on, the input voltage source supplies current to the inductor and the capacitor supplies current to the resistor (output load). When the switch is opened (providing energy is stored into the inductor), the inductor supplies current to the load via the diode D. Date
Cyril BUTTAY Schematic of a buck-boost converter I can't edit SVG files but the Vo arrow is pointing to the wrong direction, it's direction should be contrary to Vi as told by the article. Date

The buck, boost, and buck–boost topologies are all strongly related. Input, output and ground come together at one point. One of the three passes through an inductor on the way, while the other two pass through switches. One of the two switches must be active (e.g., a transistor), while the other can be a diode.
