A boy was born on a summer night in 1856, during a , which led the midwife to say, “He will be a child of the storm,” but immediately his mother to counter prophetically, “No, of the light.”

Today, we remember that boy (a child of the , his mom was right) 🙏🙏

It's death anniversary of , the father of Modern Electricity --

(7 January)

Tesla was a man who could see far into the . Although deprivileged, he died with a passion for science that changed the 20th century. Still, only a few years ago, the world started to appreciate what he did for mankind. But he wouldn’t mind it 🙏🙏

Tesla was a remarkable person. He said that he had a memory, which helped him memorize.....

The SI unit of , the tesla, named in his honor. Why is being he called a scientist? You can read a full article, here, https://www.instagram.com/cosmological_astrophysics

Top 5 Electrical Engineering Trends In 2022
Are you looking for the top 5 electrical engineering trends In 2022?

The electrical engineering industry is changing continuously. Every new year new trends and updates are coming in this field. At the beginning of 2022 itself, many ambitious research and development departments all around the world are working towards a better way to obtain, store and use electrical energy. Check the points given below & learn the top 5 electrical engineering trends In 2022.

Internet of Things (IoT)
The faster technology, 5G, makes it 5x faster than the 4th generation (4G) which enhanced IoT significantly. IoT (Internet Of Things) means a collection of “things” that are connected through the internet. Examples of IoT devices included wearable technology, smartphones, and a variety of sensors.

Drones
The use of drones goes far beyond the entertainment industry. A recent survey on some business sectors has shown the use of drones in the engineering and construction industries is increasing.

Did you know that using drones can increase safety on a construction site?

Electrical engineering service providers are using drones to examine certain hazardous electrical zones without putting themselves at risk. The Use of drones in the construction industry provides much-needed safety in the electrical engineering industry. Furthermore, drones are now helping to record, collect, and analyze data at the job site, thus increasing productivity and efficiency.

Storage Devices
Wind and solar are excellent sources of sustainable energy. However, these only work best if there are batteries, and in light of this, various electrical departments all around the world are working relentlessly towards proficient batteries.

With improved battery technologies, the industry of electric vehicles will also make significant development in 2022.

Generally, 2021 is an exciting year for the electrical engineering landscape. Companies like Tesla, Eos, Sonnen, Ola, Ather, and Vivint Solar are some companies that introduced their latest innovations in electrical storage devices last year.

OPERATION THEORY

An automatic voltage regulator (AVR) is a electronic device for automatically maintaining generator output terminal voltage at a set value under varying load and operating temperature. It controls output by sensing the voltage Vout at a power-generating coil and comparing it to a stable reference. The error signal is then used to adjust an average value of the field current.
Most cheap portable generators have fixed excitation. In such machines, when an alternator is loaded, its terminal voltage drops due to its internal impedance. This impedance is formed of leakage reactance, armature reactance and armature resistance. The Vout also depends on the power factor of the load. That's why to maintain Vout within tighter limits, more expensive models use an AVR. Note that all AVRs help regulating the output in a steady state operation, but are generally slow to respond to fast transient loads. Some high-end models, such as Honda EB10000 use more accurate digital DAVR.

Alternator voltage regulator circuit The block diagram to the right illustrates the basic concepts used in stabilizing the output of gensets with self-excited alternators. Here is how it works. When the rotor is rotated by the engine, an AC voltage is generated in the excitation winding. This AC is converted to DC by the rectifier bridge "RB"and filter capacitor "C". The detection circuit compares a voltage representing Vout with a target value and turns ON and OFF the transistor "Q". When "Q" is ON, a current flows through the field winding. When "Q" is OFF, the field current is decaying while continue flowing via free-wheeling diode "D". The rotor may include a small permanent magnet to provide some baseline current when "Q" is OFF. By properly varying duty cycle of the operation of the transistor "Q" the Vout can be regulated. Note that "Q" can also work in a linear mode, but its heat dissipation will increase.

REGULATOR SCHEMATIC

The diagram below shows a generic AVR implementation. This type of circuit has been around for years. Its numerous variations are found in both portable generators and automotive alternators and are described in various patents, such as General Motor's US3376496 for 3-phase applications and Honda's US6522106.
