Losses and costs associated with HVDC and UHVDC ... transformer. For the development of the 800 kV UHVDC system the main focus was emphasised on the equipment connected to the pole voltage, converter transformers, bushings and external insulation [3]. The converter transformers are specified to withstand switching, lightning, steep front, chopped wave voltage reversal and dc voltages [6].
Technology of a UHVDC Converter - ScienceDirect· This chapter considers the structure and working principles of UHVDC converters and the main considerations in converter connection. Since converter valves are always at the core of HVDC transmission systems, the working principles of high-power DC converter valves, including six-pulse inverters, 12-pulse converters, and the double 12-pulse converter are discussed.

It also having a big in size as compare to ...
Power inverter - Wikipedia power inverter, or inverter, is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of "converters" which were originally large electromechanical devices converting AC to DC.
