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.
The Samsung SPH-M920 (marketed as the Samsung Transform) is an Android smartphone manufactured by Samsung. It was announced on October 6, 2010 and released on October 10, 2010 for Sprint in the United States. The Samsung Transform was released using Android 2.1, but received an update to version 2.2.2 on March 25, 2011.
Certain specialized circuits can also be considered power converters, such as the flyback transformer subsystem powering a CRT, generating high voltage at approximately 15 kHz. Consumer electronics usually include an AC adapter (a type of power supply) to convert mains-voltage AC current to low-voltage DC suitable for consumption by microchips.
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 ...
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.
A line isolation transformer for telephone use is a special type of impedance matching transformer that is used to couple telephone land lines to subscriber equipment to prevent dangerous common mode voltages from appearing on the line.
