Multilevel current-source inverters have proved to be a high-performance option for industrial applications due to reliability, fault-tolerant capabilities, quasi soft switching, and the use of lower filter capacitor values. One of its major challenges is to balance the internal currents that feed each module. Imbalances could be caused by manufacturing deviations of the reactive components, temperature...
In this paper, a Model Predictive Control (MPC) strategy is applied to a Multilevel Current Source Inverter (MCSI) and its associated current source. The controller uses a discrete-time model of the entire system in order to predict the future behavior for each of the available switch states. The system is composed of a multilevel inverter, a buck converter, an output filter and a load. Each of the...
Power converters are the subject of extensive research because of their ability to work under different operating conditions, providing bidirectional power flow, high dynamic range and fast response. These advantages allow them to be used as an interface between the electric grid and many high power applications such as motors, energy storage, active filters and renewable energy sources. To be able...

Multilevel converters constitute a high performance and high reliability option for industrial applications such as motor control, transmission and distribution electrical systems, and interface with alternative energy sources and non-conventional storage systems. The biggest challenge about multilevel topologies is the balance of dividing reactive components (capacitors in voltage converters, and...
