The power electronics engineering may not be popular as other engineering forms, but it is immensely crucial for the systems that keep the world powered.
FREMONT, CA: The COVID-19 has shown the importance of engineers and the technology they develop for the world. Starting from generating power, transportation, and communication technologies to power electronics and kitchen appliances, engineers are behind such electronic devices. Here are some of the electric power systems and the way they are utilized.
Electric Power Systems
Electric power systems might look like utility power systems that were traditionally structured as the generation, transmission, and distribution of electrical energy. But the electric power system works more than that as it comprises shopping malls, air, sea, industries, shopping malls, transportation, land, and homes. There is a strong connection between the worlds of electric power systems and power electrons. Both the system is dependent on each other.
Power electronics have become an essential part of the power systems as they enhance performance and quality. It also promotes the innovative materialization of efficient and smarter energy. There are many forms in which power electronics reside power system, and here are some of them.
Electric Motor Drives
Electric motors play an essential role in generating power for domestic and industrial applications. The power electronics can control the electric motors with the help of its additional benefit of better system efficiency and dependability. Furthermore, the motor drive consists of an electric motor, a power electronic converter, and a speed and position sensor.
DC Motor Drives
Engineers use DC motors when they require a combination that contains various features like automatic torque limiting, reversing under load, continuous speed or torque, exact speed variation in line with a mechanical or electrical signal, constant acceleration, and dynamic braking.
The drives permit the stopping, reverse rotation, starting, speed control of the DC motors. The typical application is on precision machine tools like grinders and lathe in precise production operations robotics, home appliances, and other low-cost devices.
The popular converters can control the armature voltage and current of the DC motor, and it is grouped into two general groups, which are AC-DC and DC-DC. The DC supply systems are more used in traction applications and battery-powered vehicles.
