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.
There are many variations and extensions to this class of converters but these three form the basis of almost all isolated and non-isolated DC-to-DC converters. By adding a second inductor the Ćuk and SEPIC converters can be implemented, or, by adding additional active switches, various bridge converters can be realized.
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]
Integrated isoPower® isolated dc-to-dc converter. Up to four ADE7913 energy metering ICs synchronously clocked from a single crystal or an external clock. On-chip temperature sensor.
The classic Royer oscillator circuit is used in some DC–AC inverters where square-wave output is acceptable for the load. The DC-DC converter form (Royer Converter) was quite popular in the 1970s, during which time it was typically implemented with bipolar transistors. [3]
The forward converter is a DC/DC converter that uses a transformer to increase or decrease the output voltage (depending on the transformer ratio) and provide galvanic isolation for the load. With multiple output windings, it is possible to provide both higher and lower voltage outputs simultaneously.
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 ...
DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).
