Topic:

Medium-voltage drive topology design and control

Medium voltage converters are becoming more important on the market due to high power density, excellent efficiency and high reliability. Today there is a large and still growing application field for adjustable speed drives in medium voltage range such as pumps, fans, rolling mills, wind parks, and energy storage systems. In addition, the electrification of energy conversion units in transportation systems of a few tens MW tends to adopt this medium voltage drive technology. Because of a relatively large power handling capacity and severe process reliability requirement, these mediumvoltage drive systems are characterized by unique and sophisticated power converter topologies and
control features as compared to general-purpose low power drive systems. This lecture covers latest development of medium-voltage drive topology design & control techniques. The various technologies available in the market from different global manufacturers are
introduced. The selection of optimal topology and its eligible power semiconductor switches are treated in detail along with its unique switching modulation and control scheme.
