Switched DC Sources Inverterbased Shunt Active Power Filter for Power Quality Improvement
نویسنده
چکیده
A simple and reliable inverter is a prerequisite for realizing an efficient active power filter. This paper presents a reduced switch count (RSC) based asymmetrical switched dc sources inverterfor a threephase three-wire (3P3W)shunt active power filter (SAPF). The performance of considered RSCtopology is studied on seven-level asymmetrical configuration with simple level-shifted pulsewidth modulation (LSPWM) technique. Later, the dynamic performance of the consideredtopology is investigated on SAPF for compensating load generated harmonics and reactive power. MATLAB simulation results are presented to validate the compensator performance. Further, the obtained results are compared with two-level and threelevel inverter based SAPF.
