Feed-forward space vector modulation for single-phase multilevel cascaded converters with any DC voltage ratio (2008)
Journal Article
Leon, J. I., Vazquez, S., Watson, A. J., Franquelo, L. G., Wheeler, P. W., & Carrasco, J. M. (2009). Feed-forward space vector modulation for single-phase multilevel cascaded converters with any DC voltage ratio. IEEE Transactions on Industrial Electronics, 56(2), 315-325. https://doi.org/10.1109/TIE.2008.926777

Modulation techniques for multilevel converters can create distorted output voltages and currents if the dc-link voltages are unbalanced. This situation can be avoided if the instantaneous dc voltage error is not taken into account in the modulation...

Predictive current control of an induction machine fed by a matrix converter with reactive power control (2008)
Journal Article
Vargas, R., Rodriguez, J., Ammann, U., & Wheeler, P. W. (2008). Predictive current control of an induction machine fed by a matrix converter with reactive power control. IEEE Transactions on Industrial Electronics, 55(12), 4362 - 4371. https://doi.org/10.1109/TIE.2008.2006947

A different approach to perform the control of an induction machine fed by a matrix converter (MC) is presented in this paper. The proposed technique is based on predictive control and effectively controls input and output variables to the power conv...

Simplified space vector modulation (SVM) techniques for multilevel converters are being developed to improve factors such as the computational cost, number of commutations, and voltage distortion. The feedforward SVM presented in this paper takes int... Read More about Three-Dimensional Feedforward Space Vector Modulation Applied to Multilevel Diode-Clamped Converters.

Implementation of a hybrid AC-AC direct power converter with unity voltage transfer (2008)
Journal Article
Wijekoon, T., Klumpner, C., Zanchetta, P., & Wheeler, P. (2008). Implementation of a hybrid AC-AC direct power converter with unity voltage transfer. IEEE Transactions on Power Electronics, 23(4), https://doi.org/10.1109/TPEL.2008.924601

This paper presents a novel hybrid direct power converter (HDPC) which overcomes the two main disadvantages of matrix converters: limited voltage transfer ratio and low immunity to grid disturbance. The proposed converter is formed by integrating a r... Read More about Implementation of a hybrid AC-AC direct power converter with unity voltage transfer.
