A Comprehensive Harmonic Analysis and Control Strategy for Improved Input Power Quality in a Cascaded Modular Solid State Transformer
TL;DR: An in-depth theoretical analysis to investigate the input power quality of the CMSST in the presence of voltage and PBC schemes is presented and it is mathematically proven that the switching frequency based harmonics in the grid current are significantly reduced by using the PBC in stage-2.
Proceedings ArticleDOI
Analysis, modeling, design and implementation of average current mode control for interleaved boost converter
Sandeep Kolluri,N. L. Narasamma +1 more
TL;DR: Small signal modeling approach is used to develop an analytical model for average current-mode controlled interleaved boost converter and the experimental results are presented to evaluate the derived model and performance of designed controller.
Journal ArticleDOI
A New Control Architecture With Spatial Comb Filter and Spatial Repetitive Controller for Circulating Current Harmonics Elimination in a Droop-Regulated Modular Multilevel Converter for Wind Farm Application
TL;DR: A new control architecture comprising of a spatial comb filter and a spatial repetitive controller is proposed to effectively attenuate the even-order harmonics in the circulating current independent of the operating ac line frequency of the MMC.
Journal ArticleDOI
Capacitor Voltage Ripple Suppression in a Modular Multilevel Converter Using Frequency-Adaptive Spatial Repetitive-Based Circulating Current Controller
TL;DR: A new circulating current control architecture that uses the spatial repetitive controller (SRC) in both the outer voltage loop and the inner current loop, and can effectively suppress the second harmonic component of the submodule capacitor voltage ripple even under variable line frequency conditions.
Journal ArticleDOI
A Novel Open-Circuit Fault Detection and Localization Scheme for Cascaded H-Bridge Stage of a Three-Stage Solid-State Transformer
TL;DR: A novel fault detection and localization algorithm is proposed to localize the open-circuit (OC) faults (be it a single switch fault or multiple switch faults in multiple modules) in the cascaded H-bridge (CHB) stage of the SST.
