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 ...
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.
Centre for Telecommunication Research is a research-based institute at the Sri Lanka Technological Campus (SLTC) to carry out innovative, collaborative and industry-sponsored research works in wireless communications and networking. Research activities at the CTR, both fundamental and applied, mainly focus on technologies related to the ...
Etisalat (Sinhalese: එටිසලාට් Etisalat; Tamil: எடிசலாட்) (formerly known as Celltel and later Tigo), was a mobile telecommunications network in Sri Lanka. It was owned by the UAE based telecommunications operator Etisalat until December 2018.
A Flyback transformer is a high-voltage, high-frequency transformer used in plasma balls and with cathode-ray tubes (CRTs). It provides the high (often several kV) anode DC voltage required for operation of CRTs. Variations in anode voltage supplied by the flyback can result in distortions in the image displayed by the CRT.
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.
