An inverter-based resource (IBR) is a source of electricity that is asynchronously connected to the electrical grid via an electronic power converter ("inverter"). The devices in this category, also known as converter interfaced generation (CIG), include the variable renewable energy generators (wind, solar) and battery storage power stations. [1]
An and-inverter graph (AIG) is a directed, acyclic graph that represents a structural implementation of the logical functionality of a circuit or network. An AIG consists of two-input nodes representing logical conjunction , terminal nodes labeled with variable names, and edges optionally containing markers indicating logical negation .
A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). [1] The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.

The LG enV3 is a mobile phone built by LG Electronics, and released from Verizon Wireless in the United States and Telus Mobility in Canada (as the Keybo 2). It succeeded the LG enV2 . Along with a slimmer design, the enV3 also boasts a full keyboard , a 2.6-inch screen and a 3.0-megapixel camera.
Voltage transfer curve for a 20 μm inverter fabricated at North Carolina State University. Digital inverter quality is often measured using the voltage transfer curve (VTC), which is a plot of output vs. input voltage. From such a graph, device parameters including noise tolerance, gain, and operating logic levels can be obtained.
The following year saw the release of the LG Optimus 3D, the world's first mobile phone with glasses-free 3D display, [69] and LG Optimus 2X, the first with a dual-core processor. [70] In 2012 LG worked with Google to build the Nexus 4 smartphone. [71] Other than the G3, LG officially unveiled the curved smartphone, LG G Flex, on 27 October 2013.
