The National Programme on Technology Enhanced Learning (NPTEL) is an Indian e-learning platform for university-level science, technology, engineering, and mathematics (STEM) subjects. NPTEL is the largest e-repository in the world of courses in engineering, basic sciences and selected humanities and management subjects. [1]
The circuit functions as a buck-boost inverter without making use of DC-DC converter bridge due to its topology. Impedance (Z) source networks efficiently convert power between source and load from DC to DC, DC to AC, and from AC to AC. [1] [2] The numbers of modifications and new Z-source topologies have grown rapidly since 2002.
Solar inverters convert DC power to AC power and may incorporate MPPT. The power at the MPP (P mpp ) is the product of the MPP voltage (V mpp ) and MPP current (I mpp ). In general, the P-V curve of a partially shaded solar array can have multiple peaks, and some algorithms can get stuck in a local maximum rather than the global maximum of the ...
To improve the quality of higher education in India, IIT Madras came up with an initiative called NPTEL (National Programme on Technology Enhanced Learning) [58] in the year 2003. [59] As per this initiative, all the IITs, along with the IISc Bangalore would come up with a series of video lecture-based courses across all the streams of ...
It uses a high-frequency isolated DC-to-DC converter cascaded with a controllable full-bridge inverter that creates a small bipolar voltage in series with the line. The controller can control the power and compensate for accumulated voltage drop in a distribution line.
DC-to-DC converters are used in portable electronic devices such as cellular phones and laptop computers, which are supplied with power from batteries primarily. Such electronic devices often contain several sub-circuits, each with its own voltage level requirement different from that supplied by the battery or an external supply (sometimes higher or lower than the supply voltage).
In computer science, pointer swizzling is the conversion of references based on name or position into direct pointer references (memory addresses).It is typically performed during deserialization or loading of a relocatable object from a disk file, such as an executable file or pointer-based data structure.
A typical fluid catalytic cracking unit in a petroleum refinery. Fluid catalytic cracking (FCC) is the conversion process used in petroleum refineries to convert the high-boiling point, high-molecular weight hydrocarbon fractions of petroleum (crude oils) into gasoline, alkene gases, and other petroleum products.
