Optimization of switching losses and capacitor voltage ripple using model predictive control of a cascaded H-bridge multi-level StatCom (2012)
Journal Article
Townsend, C. D., Summers, T. J., Vodden, J. A., Watson, A. J., Betz, R. E., & Clare, J. C. (2013). Optimization of switching losses and capacitor voltage ripple using model predictive control of a cascaded H-bridge multi-level StatCom. IEEE Transactions on Power Electronics, 28(7), https://doi.org/10.1109/TPEL.2012.2219593

This paper further develops a Model Predictive Control (MPC) scheme which is able to exploit the large number of redundant switching states available in a multi-level H-bridge StatCom (H-StatCom). The new sections of the scheme provide optimised meth...

Space-vector-modulated three-level inverters with a single Z-source network (2012)
Journal Article
Effah, F. B., Wheeler, P., Clare, J. C., & Watson, A. J. (in press). Space-vector-modulated three-level inverters with a single Z-source network. IEEE Transactions on Power Electronics, 28(6), https://doi.org/10.1109/TPEL.2012.2219627

The Z-source inverter is a relatively recent converter topology that exhibits both voltage-buck and voltage-boost capability. The Z-source concept can be applied to all dc-to-ac, ac-to-dc, ac-to-ac, and dc-to-dc power conversion whether two-level or...
