Sažetak predavanja

Over last 50 years industrial drives have been subject to significant improvements. The development was driven primarily by the advances or power electronics devices transitioning from thyristors with soft switching commutation over silicon-based junction device (slow BJT and faster IGBTs), towards modern nowadays drives with SiC and GaN (very fast switching) channel devices. Power devices have been driving size, efficiency, and the development of power converter topologies. Operation and performances were further significantly influenced by advancements in control hardware (combinations of microprocessors and FPGAs) and control algorithms with model-based design, reaching nowadays amazing flexibility and creativity in implementation.

The talk will start with historic overview of power converters driven by technology advancements in power devices, control hardware and software/algorithms. The starting point will be availability of hard switching bipolar transistors (BJT) in the middle of 1970-ties replacing thyristors in line or load commutated soft - switching converters. The introduction of hard switching device resulted with explosion in the development of new power converter topologies. Some of the most popular in industry: nonregenerative 2 level, 3 level DC/AC, 3 phase regenerative back-to-back AC/DC/AC converters, regenerative direct frequency changes – Matrix Converters, current source, Z DC link, Vienna and resonant converters will be compared. Practical implementation, EMI, thermal management, and reliability issues as major part of the design of industrial drives will be presented. The talk will be concluded with future challenges, trends and opportunities arriving from new SiC and GaN device in drive designs.
