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.
A cheater plug, with metal grounding tab (the leftmost blade and cavity are wider, for polarization purposes). A cheater plug, AC ground lifter or three-prong/two-prong adapter is an adapter that allows a NEMA 5-15P grounding-type plug (three prongs) to connect to a NEMA 1-15R non-grounding receptacle (two slots).he use of such an adapter avoids the need to replace receptacles, but is potentially hazardous, if the grounding tab is not connected to electrical ground. An alternative identified in the US and Canadian electrical codes is to replace the outlet with a Ground Fault Circuit Interrupter (GFCI) breaker outlet.
