"Power Quality Improvement of the Distribution System using a Solid-Sta" by Md Sanwar Hossain, Md Ashib Rahman et al.
This paper demonstrates the capability of a solid-state transformer (SST) to improve the power quality of the distribution system. The three-stage 11 kV/400 V, 300 kVA, 3-phase SST discussed in this article comprises a cascaded multilevel converter-based ac/dc converter, multiple-active-bridge (MAB) converter with a high-frequency transformer acting as an isolated dc/dc converter, and a dc/ac inverter. The paper shows by simulation that the SST can address many of the power quality problems caused by grid irregularities such as voltage sag, swell, and harmonic distortion, which can cause volta...
