Facing the challenges brought by the negative sequence current (NSC) pollution in power supply system of electric railway, a new topology named half-bridge winding compensation-based railway power conditioner (HBWCRPC) without auxiliary step-down transformer is proposed to suppress the NSC injected into the public networks. It has the advantages of high integration, low losses, and more functions...
The new converter transformer and harmonic suppression scheme Filter Commutated Converter (FCC) has a unique connection mode. It is very hard to establish the coupled circuit mathematical model when the FCC only contains unaccompanied voltage sources or voltage controlled voltage sources (VCVSs), because some of their elements have no branch admittances or the impedances equals to zero. However the...
