Current Source Inverters Advantages And Disadvantages

Current Source Inverters Advantages And Disadvantages Current Source Inverters Advantages Capable of regeneration back to the a.c. line because of d.c. link polarity can be reversed. Large d.c. link filter inductor and regulated power supply act as a current limiter, making it easier to apply protective fuses. Ability to ride through power-link interruptions. The converter-grade thyristors are sufficient.  Current source inverters do not generate radiofrequency interference. Current Source Inverters  Disadvantages Cogging can occur at speeds below 6 Hz. D.C. link filter inductor is large, costly, and contributes to losses and enclosure size. Can cause high voltage spikes on motor terminals.  Usually not possible to use with more than one motor. Motor power factor appears on the incoming line to the controllers. Voltage clamping devices lower overall efficiency. It May require special tuning to motor parameters. Read More

Nothing Phone 1 Users Review

Nothing Phone 1 Users Review Can something as common as a smartphone really be reimagined? Well, many businesses, both large and small, have given it a shot during the past few years, while others, like Apple, have adhered to the tried-and-true strategy of releasing only incremental upgrades on a cyclical basis. Now, Nothing—the curiously called new company founded by Carl Pei, co-founder of OnePlus—wants to reexamine what may be done to a smartphone, and they certainly appear to be on to something. Nothing Review of a phone: What's new? It is typically difficult to complete this section of smartphone assessments, and even when we do acknowledge that a set of features is novel, they frequently don't represent real innovation. The Nothing Phone, however, is unique. The phone's look has changed, but not enough to affect the essentials. The Nothing Phone 1 has a glass rear panel that allows you to view what is inside, despite the chassis having an uncanny resemblance to an iPh

MOSFET With Zener Diode Protection

MOSFET With Zener Diode Protection  The layer of silicon dioxide between the gate and the channel is very thin and is subject to puncture by static electricity. When working with MOSFETs, special handling precautions should be taken as follows: 1. MOS devices should have their leads shorted together for shipment and storage. Conductive foam is often used for this purpose. 2. Avoid unnecessary handling, and pick up the device by the device by the case, not the leads. 3. All test equipment and tools should be connected to earth ground. 4. Workers handling MOSFET devices should have grounding straps attached to their wrists. 5. Never remove or insert MOSFET devices with the power on. Many MOSFET devices are now available with built-in more zener diode protection. Zener diodes are placed between the gate and the channel, as shown in Fig.  The voltage rating of the more zener diode is below the voltage that would cause punctures to the silicon dioxide insulator. If the voltage b

Optical Fiber, Construction, Works, Types, Uses

Optical Fiber An optical fiber cable is a kind of cable that has various optical fibers packaged together, which are regularly canvassed in their individual defensive plastic spreads.  Optical cables are utilized to exchange advanced information motions as light up to separations of many miles with higher throughput rates than those achievable by means of electrical correspondence cables.  Every optical fiber utilizes a center of hair-like straightforward silicon secured with less refractive recorded cladding to stay away from light spillage to the environment. Because of the outrageous affectability of innovation related to optical fiber, it is ordinarily secured with a high-quality, lightweight defensive material like Kevlar.  Fiber optics, or optical fiber, alludes to the medium and the innovation related to the transmission of data as light heartbeats along a glass or plastic strand or fiber.  A fiber optic cable can contain a changing number of these glass fibers - from a couple u

Multiplexer Definition, Types, Uses

Multiplexer The multiplexer is a device that has multiple  inputs and a single line output. The select lines determine  which input is connected to the output, and also to increase  the amount of data that can be sent over a network within a  certain time. It is also called a data selector. The single pole multi-position switch is a simple  example of a non-electronic circuit of the multiplexer. Multiplexers  are capable of handling both analog and digital applications. In analog applications, multiplexers are made up of relays  and transistor switches, whereas in digital applications, the  multiplexers are built from standard logic gates. When the  multiplexer is used for digital applications, it is called a digital multiplexer. Multiplexer Types Multiplexers are classified into four types: 2-1 multiplexer (I select line) 4-1 multiplexer (2 select lines) .8-1 multiplexer (3 select lines) 16-1 multiplexer (4 select lines) Uses of Multiplexers A Multiplexer is used in various applicatio

what is object in c++

What is a object in C++ Object is the essential runtime substances or fundamental unit of an object situated framework.   Object are dealt with as genuine entities which can be detected keeping in mind the end goal to comprehend it appropriately recognize anything of this world endeavor to separate its different property, the different method of its cooperation on joining every one of these qualities what we have made is an object.  Object are distinguished by their one of a kind name. an object speaks to a specific occasion of a class. There can be in excess of one example of an object. Each occasion of an object can hold its own applicable information.  4. Object may speak to a man, a place, a financial balance, or anything that the program needs to deal with.  They may likewise speak to client characterized information, for example, vector, time and records  Programming issue is broke down in term of object and the idea of correspondence between them.  Object consume up to a room r

What Is An Environment Impact Assessment || Need Of EIA || Goal Of EIA

What Is Environment Impact Assessment (EIA) It is a movement intended to recognize and foresee the contribution of the financial and biophysical qualities of the condition that may come about because of a proposition activity. it additionally helps concentrate the effect on human well-being and prosperity of authoritative proposition arrangements, developers ventures, and operational methodology and to cooperate and convey data about the effect. It is defined as the formal process used to predict the environmental consequences of any development project. Need Of  Environment Impact Assessment (EIA) It is a variable decision-making tool that indicates the alternate route of development, project site, process technology, carrying capacity of specific ecosystem & quality of environment before, during & after the proposed development activity. At is also guideless to design project which enhances the quality of the environment by examing alternatives & justifying measure throug
