Fast convergence delayed signal cancellation method for sequence component separation (2015)
Journal Article
Cardenas, R., Diaz, M., Rojas, F., & Clare, J. C. (2015). Fast convergence delayed signal cancellation method for sequence component separation. IEEE Transactions on Power Delivery, 30(4), https://doi.org/10.1109/TPWRD.2014.2373038

Delayed Signal Cancellation (DSC) is one of the methods used to separate the negative and positive sequence components in unbalanced 34 systems. In this paper a DSC methodology with a fast convergence time is proposed and is shown that an improved se...

Robustness analysis and experimental validation of a fault detection and isolation method for the modular multilevel converter (2015)
Journal Article
Shao, S., Watson, A. J., Clare, J. C., & Wheeler, P. (2016). Robustness analysis and experimental validation of a fault detection and isolation method for the modular multilevel converter. IEEE Transactions on Power Electronics, 31(5), 3794-3805. https://doi.org/10.1109/TPEL.2015.2462717

This paper presents a fault detection and isolation (FDI) method for open-circuit faults of power semiconductor devices in a modular multilevel converter (MMC). The proposed FDI method is simple with only one sliding mode observer (SMO) equation and...

Grid Parameter estimation using Model Predictive Direct Power Control (2015)
Journal Article
Arif, B., Tarisciotti, L., Zanchetta, P., Clare, J. C., & Degano, M. (2015). Grid Parameter estimation using Model Predictive Direct Power Control. IEEE Transactions on Industry Applications, 51(6), https://doi.org/10.1109/TIA.2015.2453132

This paper presents a novel Finite Control Set Model Predictive Control (FS-MPC) approach for grid-connected converters. The control performance of such converters may get largely affected by variations in the supply impedance, especially for systems...

Self-tuning resonant control of a 7-leg back-to-back converter for interfacing variable speed generators to 4-wire loads (2015)
Journal Article
Cardenas, R., Espina, E., Clare, J. C., & Wheeler, P. (2015). Self-tuning resonant control of a 7-leg back-to-back converter for interfacing variable speed generators to 4-wire loads. IEEE Transactions on Industrial Electronics, 62(7), https://doi.org/10.1109/TIE.2015.2409803

This paper considers the control of a 7-leg back-to-back Voltage Source Inverter (VSI) arrangement feeding a 4-wire load from a 3-phase Permanent Magnet Synchronous Generator (PMSG) operating at variable speed. The PMSG is controlled using a sensorle... Read More about Self-tuning resonant control of a 7-leg back-to-back converter for interfacing variable speed generators to 4-wire loads.

Experimental comparison of a matrix converter using Si IGBT and SiC MOSFETs (2015)
Journal Article
