Power Electronics: It is the technology which has seen a lot of advancements in recent times and has impacted human life in almost every sphere. We over selves use so many applications in our daily life, without realizing it. Controlling the flow of electrical energy by switching electronic circuits is what is known as Power Electronics. It is the technology which is behind the concept of power inverters, motor drives, switching power supplies, power converters and so on.
Applications of power electronics
We can realize the application everywhere in our daily lives such as office, home, factory, car, hospital and so on.
Typical applications: Such as Industrial process in chemical, steel and paper industries, generation and transmission control, motor drives from washing machines, food mixers, power supplies for laboratories.
Consumer applications: As a matter of fact, this type of applications covers several areas in the home such as heat controls, light dimmers, security stream, audio amplifiers and motor control for food mixers and power tools.
Transportation applications: Motor drives for electric vehicles, and locomotives. Additionally, non-motor drive applications such as vehicle electronic ignition, vehicle voltage regulation, and traffic signal control.
Aerospace applications: Aerospace and defense applications include power supplies for space and aircraft, VF transmitters, switching using solid relays and contractors.
Industrial applications: It mainly consists of two areas such as power supplies and motor control. The motor which can control varies from large to small ones. As well as power supplies are utilizing for battery charging, electroplating, welding, Web Service and induction heating.
Power Electronics: Technology That Makes The Modern World
The traditional application areas of power electronics are variable speed drives for electrical motors. It can vary the speed of motor drives, making in processes more efficient and reducing the amount of energy consumed. Without power electronics inverters, the motors running these systems would continually be running at consuming vast amounts of unnecessary energy.
In the case of solar energy, power electronics inverters make it possible to transform DC energy produced by a solar panel into AC. It can then be fed into a commercial electricity grid. In fact, a similar conversion from direct current to alternate current is needed for wind energy. It must be fed into the grid at the constant frequency, despite, fluctuating wind conditions.
Another area where it can deliver significant energy savings in data centers. More than a third of the energy used in the Big Data Projects center goes on cooling. Using variable speed drives to air conditioners and pumps, the rate of these systems can adjust to match the amount of cooling needed.
