Matrix converter open circuit fault diagnosis with asymmetric one zero SVM (2017)
Presentation / Conference Contribution
Zhang, J., Empringham, L., De Lillo, L., Dan, H., & Wheeler, P. Matrix converter open circuit fault diagnosis with asymmetric one zero SVM. Presented at 2017 IEEE Energy Conversion Congress and Exposition (ECCE)

An open-circuit fault detection and diagnosis strategy for a direct matrix converter is proposed in this paper. The current recirculating path during an open circuit condition is considered in detail with the aim of contributing more expert knowledge...

Differential buck single phase grid connected AC-DC converter with active power decoupling using a flipping Capacitor (2017)
Presentation / Conference Contribution
Gottardo, D., De Lillo, L., Empringham, L., & Costabeber, A. Differential buck single phase grid connected AC-DC converter with active power decoupling using a flipping Capacitor. Presented at 8th International Symposium on Power Electronics for Distributed Generation Systems (PEDG 2017)

This paper introduces a new single-phase AC-DC converter capable of achieving independent voltage control across a dedicated power decoupling capacitor, by exploiting the same full bridge that controls the grid current in combination with two bidirec...

Control of a direct matrix converter with modulated model predictive control (2017)
Journal Article
Vijayagopal, M., Zanchetta, P., Empringham, L., De Lillo, L., Tarisciotti, L., & Wheeler, P. (2017). Control of a direct matrix converter with modulated model predictive control. IEEE Transactions on Industry Applications, 53(3), 2342-2349. https://doi.org/10.1109/TIA.2017.2674602

This paper investigates the use of a model- predic-tive control strategy to control a direct matrix converter. The proposed control method combines the features of the classical Model Predictive Control and the Space Vector Modulation technique into...
