This paper is devoted to development and investigations of an inverter-fed interior permanent magnet synchronous motor (IPMSM) drive for battery electrical vehicles (BEV). The main purposes are comparative investigation of two torque and speed control algorithms: vector control (FOC) and model predictive control (MPC) both with and without maximum torque per ampere algorithm. The theoretical consi...Show More
Integrated circuits, flat panel displays, solar panels, architectural glass, high resolution camera and many other products are landmarks of the 21st century. All of these different everyday objects have one thing in common - they are manufactured using plasma processing techniques. The aim of this paper is to introduce this silent hero of modern industry, to a broader audience. An evaluation is m...Show More
In this work, we proposed an encoderless finite control set predictive flux control (FCS-PFC) method for an induction motor (IM) fed by a three-level neutral-point clamped (3L-NPC) power converter. The FSC-PFC employs stator flux vector as control objective to eliminate the weighting factor(s) between torque and flux commonly used in the predictive torque control (PTC) approach. An improved slidin...Show More
A direct-drive permanent magnet synchronous generator (PMSG) with a three-level neutral-point-clamped back-to-back power converter is an attractive configuration for high-power wind energy conversion systems. For such a topology, finite-control-set model-predictive control (FCS-MPC) has emerged as a promising alternative. However, due to its fully model-based concept, variation of system parameter...Show More

The paper presents a multilevel cascaded H-bridge 5-level converter with boosting capability. Standard solution for boosting voltage in power electronic devices is utilization of a dc-dc converter with a bulky inductor. However, inductor is a problematic component of a power electronic converter because usually it needs to be individually designed and produced for every device and also because its...Show More
