The flyback (the vertical portion of the sawtooth wave) can be a potential problem for the flyback transformer if the energy has nowhere to go: the faster a magnetic field collapses, the greater the induced voltage, which, if not controlled, can flash over the transformer terminals. The high frequency used permits the use of a much smaller ...
Logo used until 2015. Samsung Galaxy (Korean: 삼성 갤럭시; stylized as SΛMSUNG Galaxy since 2015 (except Japan where it omitted the Samsung branding up until 2023), [2] previously stylized as Samsung GALAXY; abbreviated as SG) is a series of computing, Android mobile computing and wearable devices that are designed, manufactured and marketed by Samsung Electronics since 29 June 2009.
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.

Celltel was founded on 18 June 1989 on a Motorola TACS system, becoming the first cellular network in Sri Lanka and 36th operator in world. [5] It was then re-branded by Millicom International in January 2007, as Tigo (Sri Lanka). then it was acquired by Etisalat.
It was the 3rd largest fixed wireless operator and the 3rd largest fixed phone operator with an island wide digital wireless network in Sri Lanka. Lanka Bell was formed in 1997 as the single largest BOI Company in Sri Lanka with an investment of over US$150 Million. It was subsequently acquired by the privately held diversified conglomerate ...
Being a center for trade in the Indian Ocean since antiquity, however, the history of collection of customs duties in Sri Lanka dates far back as the second century BC. [citation needed] "According to the inscription of King Gajaba I (112-134 A.D.) the customs duty collected from the Godapavata Harbour had been donated to the Godapavata monastery.
