Power Electronics – How it Works
Power electronics converts electrical power from one form to another. A lot of energy is wasted during this power conversion process due to the efficiency conversion of low power. It is estimated by the students of top BTech colleges Jaipur that power wasted in desktop PCs sold in one year is equivalent to seventeen 500MW power plants. Therefore, it is very important to improve the efficiency of these power conversion systems.
The electric machine is an electromechanical energy conversion device that works and delivers power to the load. The same electric machine can operate as a motor to convert electrical power to mechanical power directly and can operate as a generator to convert mechanical power to electrical power. The electric machine is related with the power electronic converter and the related controller makes the motor drive. The power electronic converter is made of solid-state devices that handles power from the source to the motor input terminals.
A research has been conducted by the students of Electronics and Communication Engineering Colleges which shows that the area of electric machines and drives is focused on design optimization. It uses 2D and 3D finite element analysis, and drives design at the systems level by considering operating requirements and control opportunities. It seeks innovations in machine configurations, motor control concepts, noise, parameter identifications, vibration analysis. Motor drives are designed to make the system more efficient, smoother in operation, fault tolerant, smaller and matched to the applications. Modeling and design tools are developed to fulfil the machine design and drive development efforts.
1. Electric Vehicle Systems
Within a single century, the demand for private automobiles has been increased. It is projected that the need for personal mobility among the students of Top BTech Colleges Rajasthan will grow even faster, as large numbers of people are lifted out of poverty in developing countries and demand transportation. Emissions from oil-burning automobiles blocks our air and contribute to global warming. Due to this, finding an alternative to oil for private transportation is imperative. Although several alternatives can propel a car, only electricity is readily available.
With the introduction of electric propulsion, a completely new drive-train is introduced in the vehicle which requires multidisciplinary research into system components. The Electric vehicle system is comprised of power electronics converters, electric motor, and energy storage devices like batteries. Additionally, the overall system must be optimized to maximize overall system efficiency.
2. Electronic Energy Systems Packaging
Electronic Energy Systems Packaging encompasses technologies that focuses on the physical implementation of energy storage systems and power electronic. Electrical engineers of best engineering colleges in Jaipur develop circuits and schematics. It is delivered to a customer are electro-physical circuits concurrently combined and designed into a hardware system. These hardware systems must meet metrics like weight, power, and size densities; government and industry standards; and reliability.
This research is broad-based and multidisciplinary with studies in magnetic, electric, thermal and mechanical components and circuits. Students of Engg colleges focuses on high-frequency, high-density topologies that use ultrafast-switching power semiconductors, and the materials and fabrication processes create such topologies.
Applications are in new integrated power systems ranges from chip to ship like land-based smart grid power systems, electric vehicle converters and drives, high performance power supplies for aerospace, telecom and DC distribution systems, and ultrafast fault protectors using the latest in various semiconductors.
3. Power Electronics
The technology of Power electronics is associated with the efficient control, conversion, and conditioning of electric power by static means from its available input form into the desired electrical output form. Power electronic converters do not require modifying the electrical energy form. With “classical” electronics, electrical currents and voltage are used by the students of Top Private Engineering Colleges in Rajasthan to carry information, whereas with power electronics, they carry power.
A research has been conducted by the students of engineering colleges Jaipur in this area. It includes power electronics applications to control large scale power transmission and distribution with the integration of distributed and renewable energy sources into the grid.
4. Power Management ICs
Power management ICs are used by the students of top MTech colleges in Jaipur to manage the accurate power flow in portable and handheld devices like cell phone power amplifiers and LED display, Graphics, CPU, DRAM, High Speed I/O and USB. Additionally, under-voltage or other fault conditions are monitored to prevent damage to the system. The soft-start feature reduces stress on power supply components and increase the reliability of product. Typically, implementation is done using analog integrated circuits but there is a strong trend to move towards digital or mixed signal implementation.
5. Power Semiconductor Devices
Power semiconductor devices are mainly semiconductor devices used as switches or rectifiers in power electronic circuits. Also, they are called as power devices or when used in integrated circuits, called power ICs. A research has been conducted by the students of top MTech colleges to increase the maximum power handling capability of the power devices. On the other hand, it includes the need to increase the speed they can switch. Also, power semiconductor is the key in determining the power conversion efficiency.
6. Power Systems
Electric power systems are comprised includes the components that produce electrical energy and transmit this energy to consumers. A modern electric power system consists of different components like power plants which generate electric power, transformers which raise or lower the voltages as needed, transmission lines to carry power, substations at which the voltage is stepped down for carrying power over the distribution lines, and distribution transformers which lower the voltage to the level needed for the consumer equipment. The electricity production and transmission are relatively efficient and inexpensive. Although unlike other forms of energy, electricity is not easily stored, and must be produced based on the demand.
