PROJECT TITLE :

The Essential Role and the Continuous Evolution of Modulation Techniques for Voltage-Source Inverters in the Past, Present, and Future Power Electronics

ABSTRACT:

The cost reduction of power-electronic devices, the increase in their reliability, efficiency, and power capability, and lower development times, along with more demanding application necessities, has driven the event of many new inverter topologies recently introduced within the business, particularly medium-voltage converters. New a lot of complicated inverter topologies and new application fields come back together with further control challenges, such as voltage imbalances, power-quality problems, higher efficiency wants, and fault-tolerant operation, that essentially needs the parallel development of modulation schemes. Thus, recently, there have been vital advances in the sphere of modulation of dc/ac converters, that conceptually has been dominated throughout the last many decades nearly solely by classic pulse-width modulation (PWM) methods. This paper aims to concentrate and discuss the latest developments on this exciting technology, to provide insight on where the state-of-the-art stands these days, and analyze the trends and challenges driving its future.
