LABORATORY OF CONVERSION OF ENERGIES AND ELECTRONICS OF POWER
Lines of investigation

A. Design and construction of power converters

In order to validate the control strategies proposed by the research group, low power teams are designed, assembled and built, in order to evaluate new techniques. The objective is to emulate a real scenario on the laboratory, and observe the behavior of these equipments.


B. Digital control of power converters

Due to the accelerated technological advance, new control platforms are appearing on the market constantly. These are not only faster, but also offer wider storage capacity. The LCEEP seeks to maintain the technological avant-garde with its equipment to implement the proposed control techniques, while also ensuring their economic value.


C. Matrix converters

The matrix converters are ac / ac frequency converters that directly connect the input source to the output without an energy storage element. In the LCEEP, this line of research has been developed in recent years, where the main topics are focused on the control of different topologies of matrix converters, new configurations of matrix converters and new applications of these converters.

D. Wind power generation systems

Technological development in Chile has led to an increase in the demand for electricity. As known, Chile is entitled as a poor country regarding the generation of energy, since it has little gas, oil and coal, situation which raises the costs of energy and affects the country’s competitiveness. Notwithstanding, this lack of fossil energy has stimulated the penetration of renewable energies, as well as the search for more profitable, efficient and reliable solutions. Within the lines of research developed in the LCEEP in this subject are synchronization, power control and operation against disturbances of different configurations.


E. Integration of renewable energies to the electricity grid

The integration of renewable energies such as solar and wind power with the existing grid requires electronic devices which will serve as an interface between generators and energy consumers. To this matter, different configurations and control strategies are developed to optimize the energy transfer.


F. Predictive control in power converters and drives 

The predictive control in power converters and drives has been a topic of research and development in the last 3 decades. The objective is to use a mathematical model of the system to predict the behavior of the variables to be controlled in the next sampling moment for each of the valid states of the converter. This prediction is compared to a reference in a cost function for each valid switching state. The switching state that generates the minimum value in the cost function is the one that will be selected to be applied to the converter at the next sampling time. The LCEEP has published several articles in this area and has focused research on different topics:
  • New control techniques for different converter configurations: three-phase, multiphase, multilevel, modular inverters, etc.
  • Predictive control of current, voltage, power, torque and speed.
  • Predictive control in different applications such as: active filters, wind power generation systems, drives, etc.
