A new concept of convertor design is proposed suitable for large current ratings, such as used in back-to-back HVDC interconnections. It consists of a parallel 12-pulse configuration involving two phase shifted bridges and a thyristor-tapped interphase reactor. The dc. ripple present across the interphase reactor is used to derive a current waveform which, when added to the original phase currents, effectively doubles the converters pulse number. It is shown theoretically and experimentally that the use of dc.-ripple reinjection achieves 24-pulse operations from a conventional 12-pulse HVDC converter configuration.
