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...

Modulated Model Predictive Control for a Three-Phase Active Rectifier (2014)
Journal Article

Model predictive control (MPC) has a number of desirable attributes which are difficult to achieve with classical converter control techniques. Unfortunately, the nature of power electronics imposes restriction to the method, as a result of the limit... Read More about Modulated Model Predictive Control for a Three-Phase Active Rectifier.

DC fault ride-through capability and STATCOM operation of a HVDC hybrid voltage source converter (2014)
Journal Article

HVDC transmission systems are becoming increasingly popular when compared to conventional AC transmission methods. HVDC voltage source converters (VSC) can offer advantages over traditional HVDC current source converter topologies; as such, it is exp...

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...
