“…As it is known, the effects of the conduction angle over the power factor, come from the current delay caused by the firing angle ( α ) [2][3][4][5][6][7][8][9][10]. The auxiliary converter is activated during periods of time in which the HVDC converter is inoperative, in order to compensate its inherent inductive effect.…”

This paper intends to discuss some practical results of the reverse-use of the harmonic distortion energy from idle periods in conventional HVDC converters. It is shown that this energy can be used to reduce the total harmonic distortion, and so, the costs of harmonic filters, and to increase the power and utilization factors. The technique is based on the diversion of harmonic currents from a conventional HVDC converter to make it go through an auxiliary power converter with special features.
