A MODULAR VOLTAGE SOURCE CONVERTER

摘要

Voltage source converter based on a chain-link cell topology, said converter comprising one or more phases (L1, L2, L3), each of said phases comprising one or more series- connected chain- link cell modules connected to each other, an output voltage of said voltage source converter is controlled by control signals applied to said cell modules. In case of failure of a chain- link cell module that module is controlled, by said control signals, such that zero output voltage is provided at its output voltage AC terminal.
