Harmonics and unbalanced load compensation by a modular multilevel cascaded converter active power conditioner

Blog Article

This paper presents a novel control scheme for a modular multilevel cascaded converter (MMCC) functioning as an active 1980 corvette tail lights power conditioner (APC) to control the reactive power, eliminate the current harmonics, and compensate unbalanced load current simultaneously.This combines a modified predictive current controller with the inter-cluster and intra-cluster voltage balance control for MMCC sub-module capacitors.Simulation studies of this MMCC-APC for a power gu502lv-bi7n8 network containing both an unbalanced thyristor controlled rectifier and a reactive load are performed and results verifying its performance under varying degrees of load current distortion measured by THD levels are presented.
