Comparison of non-isolated switching DC-to-DC converter topologies: Buck, Boost, Buck-Boost, Ćuk. The input is left side, the output with load is right side. The switch is typically a MOSFET, IGBT, or BJT transistor. The Ćuk converter [1] (Serbo-Croatian:, English: / ˈ tʃ uː k /) is a type of buck-boost converter with low ripple current. [2]
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 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 ...
Switch-Mode Power Supply Tutorial - Detailed article on DC-DC converters which gives a more formal and detailed analysis of the Buck including the effects of non-ideal switching (but, note that the diagram of the buck-boost converter fails to account for the inversion of the polarity of the voltage between input and output).
The term push–pull is sometimes used to generally refer to any converter with bidirectional excitation of the transformer. For example, in a full-bridge converter, the switches (connected as an H-bridge ) alternate the voltage across the supply side of the transformer, causing the transformer to function as it would for AC power and produce a ...
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 bidirectional transient-voltage-suppression diode can be represented by two mutually opposing avalanche diodes in series with one another and connected in parallel with the circuit to be protected. While this representation is schematically accurate, physically the devices are now manufactured as a single component.
