Harmonic Distortion Elimination for STATCOM Application Using SHE-PWM Cascaded Multilevel Inverter
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2016, Vol 4, Issue 3
Abstract
A novel multilevel selective harmonic elimination pulse-width modulation (MSHE–PWM) technique for transformer static synchronous compensator STATCOM system using cascaded H-bridge inverter (CHI) is proposed. MSHE–PWM method optimizes both the dc voltage levels and the switching angles, helping more harmonics to be eliminated without affecting the structure of the inverter circuit. The converter is operated by maintaining the switching frequency of a converter to a minimum value using a technique called (SHE-PWM).Rapid growth and development in the field of power semiconductor devices resulted in production of high efficiency dc to dc converters with a relatively high-voltage capacity and for simplicity, a buck dc to dc converter is considered in this project. The simulation study is tested in MATLAB to understand the performance of the proposed scheme.
