Overview

DSPyC is the acronym of Departamento de Sistemas de Potencia y Control (Department of Power and Control System). DSPyC is an organization under the supervision of the Engineering Faculty of the National University of Asunción (FIUNA), integrating undergraduate courses related to power electronics and control field. Thanks to its advanced infrastructure and last generation instrumentation equipment, DSPyC leads Research, Development and Innovation (R&D+i) project focused on renewable energy and power quality. These projects focused their objectives in improving the power quality of wind generation systems, hydraulic mini power plants, solar photovoltaic, solar thermal and energy saving. In all cases, oriented to covering the needs nationwide.

Moreover, DSPyC provides engineering and consulting services based on the knowledge and application of cutting edge electronic technology, to address problems associated with the industrial sector mainly in implementing control technology to power electronic equipment. These devices are used on a multitude of industrial applications in energy, manufacturing, aeronautics, naval and others.

From DSPyC through FIUNA, we are convinced that Paraguay can not be dissociated from the worldwide technological advances in terms of renewable energy and power quality, and we recognize that the current energy scenario should be diversified toward sustainable technologies with proven performance, such as renewable energy and decentralized cogeneration, mainly considering the abundant, clean and unlimited renewable resources nationwide.
