Unit Code: PHY924

Unit Name: Power Electronics for Renewable Energy Systems

Description: Global electrical energy consumption is still rising and there is a steady demand to increase power capacity. It is expected that it has to be doubled within 20 years. The production, distribution and use of the energy should be as technologically efficient as possible and incentives to save energy for the end-user should also be set up. Deregulation of energy has lowered the investment in larger power plants, which means the need for new electrical power sources may be very high in the near future. Two major technologies will play important roles to solve future problems. One is to change the electrical power production resources from conventional, fossil (and short-term) based energy sources to renewable energy resources. Another is to use highly efficient power electronics in power generation, transmission, distribution, and end-user applications. This course provides an insight into circuitry for the control and conversion of electrical power with high efficiency and begins analysis with switched-mode power converters. These converters can change and regulate the voltage, current, or power; dc-dc converters, ac-dc rectifiers, dc-ac inverters, and ac-ac cyclo-converters are in common use. Applications include electronic power supplies, aerospace and vehicular power systems, and renewable energy systems. The course is developed in line with Sustainable Development Goals (7, 8, 9, 11, & 12).

Learning Target Outcomes: The course will involve theoretical and practical aspects. As a result of successfully completing this unit, the students will be able to: 1. Synthesize basic semiconductor physics to properties of real devices, and combine circuit mathematics and characteristics of linear and non-linear devices to formulate and analyse system designs. 2. Implement skills in engineering estimation to analyse real-world situations, identify the important features and develop a valid approach to the solution. 3. Evaluate a power electronic circuit design at the systems level. 4. Demonstrate the basic principles, advantages and limitations of computer simulations of circuit behaviour, and apply these technique to simple power linear and non-linear electronic circuits. 5. Explain the static and dynamic characteristics of power semiconductor devices. 6. Distinguish the working principle of uncontrolled and controlled rectifiers and calculate the input, output and device currents.
