An American Rotary Phase Converter with a Transformer. A phase converter is a device that converts electric power provided as single phase to multiple phase or vice versa. The majority of phase converters are used to produce three-phase electric power from a single-phase source, thus allowing the operation of three-phase equipment at a site that only has single-phase electrical service.
LM393 differential comparator manufactured by National Semiconductor. The following is a list of LM-series integrated circuits.Many were among the first analog integrated circuits commercially produced since late 1965; [1] some were groundbreaking innovations [opinion].
In 1974, Hodges and Gray worked with R.E. Suarez to develop MOS switched capacitor (SC) circuit technology, which they used to develop a digital-to-analog converter (DAC) chip, using MOS capacitors and MOSFET switches for data conversion. [22] MOS analog-to-digital converter (ADC) and DAC chips were commercialized by 1974. [23]
The single-ended primary-inductor converter (SEPIC) is a type of DC/DC converter that allows the electrical potential at its output to be greater than, less than, or equal to that at its input. The output of the SEPIC is controlled by the duty cycle of the electronic switch (S1).
Live election results from The Huffington Post. Romney vs. Obama, Senate, House and ballot measures.
Articles with the IC number in the title use [[Category:IC objects|####]], dropping the IC prefix, and using only the number. The number should be padded up to 4 digits using zeroes. Articles without the IC number in the title use [[Category:IC objects]]. A redirect containing the IC number should also be added to the category, sorted as above.
Consumer voltage converters (also known as "travel converters") are used when traveling between countries that use ~120 V versus ~240 V AC mains power. (There are also consumer "adapters" which merely form an electrical connection between two differently shaped AC power plugs and sockets , but these change neither voltage nor frequency.)
