Research Projects
- Advanced Controllers: Digital non-linear control strategies that enable intelligent power conversion. State Plane controllers guarantee a fast, reliable and stable response to commands and external perturbations. By employing accurate modelling techniques, the converter response can be predicted, ensuring direct convergence towards the target. Advanced control methods enable fast transient responses while maintaining a reliable operation. Advanced digital control enables size reduction on reactive components.
- Renewable Energy Systems: Special power converters and advanced algorithms enable the cost-effective adoption of renewable energy. Real time execution of control and optimization algorithms using digital signal processors for a new generation of power conversion. Novel algorithm and model development to improve solar, wind and tidal energy harvesting under fluctuating environmental conditions. Development of smart control algorithms for converter and system level devices that interfaces distributed generation, energy users and storage. Optimal system design and operation strategies focusing on distributed generation, energy storage and islanded/grid-tied operation.
- EV Battery Chargers: High-efficiency ultra compact battery chargers for new generation electric vehicles. Simple but precise modifications to well-known topologies allows for new architectures capable of improving battery charging for EV applications. Contrasting with usual battery chargers, the developed models regulate the output voltage in a wider range under different loading conditions. By eliminating discontinuous charging mode and providing higher quality charging current, the life cycle of batteries is increased, and a noise-free environment for reliable battery management system (BMS) operation is achieved. Increased Power Density. Elimination of auxiliary circuits, lower conduction and switching losses, and reduced passive elements allow for smaller boards which transfer the same amount of power.
