The goal of this subject is to provide the student with a multidisciplinary and solid knowledge in every aspect involved in the design, selection, and operation of power converters and power electronics systems Along the subject, special attention will be paid to identify and justify the best converter topologies, modulation techniques, control strategies, power semiconductor devices, and magnetic components, applied to transform the electrical energy. In order to achieve this goal, the student will acquire the following specific skills: - Ability to identify the best power semiconductor for each type of application. - To know which are the best converter topologies for each type of energy conversion: DC-DC, DC-AC y AC-DC. - To know the figures of merit that drives the design and optimization of the power converters. - To know the improvements and potential advantages of the most advanced topologies that are currently used in the electrical energy conversion systems. - Ability to develop the dynamic modeling of a power converter, from a practical point of view. - Ability to design in practice the current control loop of a power converter. This control technique is used in most of the control systems of power electronics converters applied to energy conversion. - To know the basic protection techniques and thermal management techniques used in power converters. - To know how Power Electronics is an enabling technology in most of the current energy applications In terms of general abilities or skills, the following areas will be worked upon throughout the development of the subject: - Ability to design and conduct experiments and to analyze and interpret the results. In particular, this capability will be dealt with during the laboratory practical sessions. - Ability to work cooperatively in a team, knowing how to adapt the requirements and working conditions of the subsystem developed so that they operate correctly within a global system which is not only electronic. This aspect will be covered by means of the development of examples and case studies. - Ability to identify, formulate and solve problems in Engineering. - Ability to use the techniques and tools required in modern engineering to reduce the equipment development time.

The subject is divided into three main blocks: Block 1: Power Electronics applied to electrical energy production and management. - Power supply systems in transportation. Railway, electric cars, aerospace. - Power converters in renewable energy systems: Photovoltaics, wind power, wave energy. - Uninterrupted Power Supplies. - Energy recuperation systems. Block 2: Components and topologies - Review of basic electrical concepts and commonly used mathematical tools. - DC-DC converters. - Rectifiers (AC-DC). - Inverters (DC-AC). - Advanced topologies applied to energy conversion: multilevel converters and modular converters. - Power losses and heat-sinks. - Electrical protections. Block 3: Control techniques in power converters. - Dynamic modeling fundamental. - Control loop design. - Digital control techniques. - Control of a grid-tied three-phase inverter.

The teaching methodology will include:: - Magisterial Classes (3 ECTS), where the students will be presented with the basic knowledge they must acquire. Students will be supplied with lecture notes and key reference texts that will enable them to complete and acquire a more in-depth knowledge of the subject. - Problems Classes and Laboratory Classes (3 ECTS) these are aimed at the solving of exercises and examples within the context of real case studies. These classes will be complemented with the resolution of practical exercises on behalf of the student that in some cases may require the use of computer-based simulation programs. The Laboratory classes will be developed taking into account a double methodology. In the first session, the student will design mount and measure a real DC ¿ DC converter. In the next sessions, students will use the most convenient CAD tools applied to design and simulate power converters such as grid-tied inverters. - Group tutorial: At least a group tutorial will be carried out the recovery week as revision and final exam preparation. - Among all these activities, 2.4 ECTS corresponds to in-class sessions.
