The conventional tripole HVDC system, which uses thyristor converters, has some inherent defects. This paper proposes an improved scheme which uses the full-bridge submodules-based modular multilevel converters to replace the thyristor converters in pole 3, and the converters in pole 1 and 2 are also replaced by the modular multilevel converters based on half-bridge submodules. In order to obtain...
