Matrix converter based compensator for unbalance mitigation in traction system

Abstract

Modern AC Electric trains are designed as single-phase loads and are operated on the three-phase utility grid which causes load asymmetry and leads to unbalanced current flow in the three-phase grid. Several traction unbalance compensators have been proposed in literature. However, most of them include a large DC link capacitor, which is notorious for its high rate of failure. This paper presents the topology and the control algorithm of a matrix converter based traction unbalance compensator. The proposed topology does not incorporate any DC link capacitor and therefore is very reliable compared to several compensators proposed in literature. The efficacy of the proposed compensator is demonstrated by simulation in MATLAB/Simulink environment.
