In the field of mathematics, corresponding sides usually refers to the sides of two plane figures corresponding to one another. For example consider the two figures below: As we can see both the above figures are pentagons.
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.herefore the operating principle of both converters is very close: 1  When the switch is closed (top of Fig. 2), the primary of the transformer is directly connected to the input voltage source. 2  When the switch is opened (bottom of Fig. 2), the primary current and magnetic flux drops.
The basic difference between a regular transformer and a flyback transformer lies in the design and construction of these devices. The later stores the input power during one phase of operation and then generates the âkick backâ voltage during another phase.This energy is stored temporarily in a magnetic field inside the flyback transformer. Flyback transformer operates at frequencies ranging from 20 KHz to 200 KHz.he later stores the input power during one phase of operation and then generates the âkick backâ voltage during another phase. This energy is stored temporarily in a magnetic field inside the flyback transformer.
