Operating characteristics of a new filter-commutated converter based on equivalent Graetz bridge circuit model

In this study, filter-commutated converter (FCC) with a new topological structure is proposed and compared with conventional high-voltage DC converters. The characteristic harmonic filters are installed at the tap of valve winding, which can implement the harmonic suppression and the reactive power compensation near the valve side. Based on multi-winding transformer theory and Kirchhoff's law, the...
