A Study of Modified Space Vector PWM Based Algorithm for Multilevel Inverter

Akhilesh Kumar Tripath, Imran Khan

Abstract


This paper describes a multilevel inverter for renewable energy systems. The study is carried out for three different cases. In the first case, one of the two dc-link capacitors of the inverter is replaced by a battery bank and the other by a supercapacitor bank. In the second case, dc-link capacitors are replaced by two battery banks. In the third case, ordinary dc-link capacitors are replaced by two supercapacitor banks. The first system is supposed to mitigate both long-term and short-term power fluctuations while the last two systems are intended for smoothening long-term and short-term power fluctuations, respectively.

Keywords: multilevel inverter, PWM, renewable energy, super capacitor
