Abstract
Power Electronics is a fundamental technology in several areas, and particularly in industrial systems. In power electronics conversion
systems, the multilevel technology has provided several advantages: higher efficiency, lower harmonic distorsion, higher fault tolerance
capacity, higher rated power for a given semiconductor device technology, the capability to operate with economical semiconductor
swiching devices with very good electrical performance features, etc.
Among the different multilevel topologies, the recently proposed and so called multilevel active-clamped (MAC) topology features a great
potential in terms of compacity, since it does not need energy storage elements within the converter legs. In addition, it preserves the
efficiency and harmonic distortion advantages inherent to multilevel conversion. Combining multilvel active-clamped legs, one can
configure dc-dc, dc-ac (operated in both inverter and rectifier modes), and ac-ac converters.
This Project proposes to introduce hardware enhancements into the multilevel active-clamped leg, and develop new modulation and
control techniques for the converters build up upon these legs. The goals pursued are: to improve the efficiency, to improve the loss
distribution among devices, to improve the reliability, to improve the fault tolerance, to enable the use of this technology with the Si and SiC
devices with which it has not already been applied, to extend the use of this technology to the conversion configurations to which it has not
been applied yet, and to improve the performance features of the sytems where these converters are integrated.
The intention is that the technology developed within the Project be of general interest for several applications. However, its advantages
will be experimentally evaluated with scaled prototypes in two especific applications: in the system consisting of a wind generator
connected to the grid and in the traction system of an electric vehicle. Other applications where the developed technology can be specially
competitive will also be identified.
It is expected that the knowledge generated within the Project contributes to a change of the paradigm in power electronics design,
consisting of the design of conversion systems from a reduced set of highly optimized and economical devices, which combined into
multilevel or multicell topologies, allow to implement the different electronic conversion systems, improving their performance features,
volume, weight, and cost, in comparison to the current technology.
The industrial and institutional partners of the Project are: ABB, Agencia de Energía de Barcelona, Alstom Wind, Gas Natural Fenosa,
General Electric, Iberdrola, and Semikron.
