“…Secondly, most previous works assume that a stiff dc-link is applied [11] [13]. In reality while only finite dc-link capacitors can be installed, some proposed modulators may lead to unbalanced ampere-second in the dc-link.…”

“…open-loop selection of redundant states for the modulators. Some papers propose to distribute the switching events instantaneously to balance the pulse number between the legs [11]. However, it seems that few papers analyze and state when such modulators with redundancy can work reliably at open-loop, and when the redundant states of the modulator should be actively and smartly assigned to the two legs to balance the circuit, using a closed-loop modulator with online pulse distribution.…”

This paper demonstrates the impact of modulation schemes on the power capability of a high-power converter with low pulse ratios. This IGCT converter uses a five-level Neutral-Point-Clamped H-bridge topology. It is concluded that phase-shifted carrier modulators are not attractive for such converters at low pulse ratios due to the poor THD (Total Harmonic Distortion) performance and poor power capability. The THD performance is a key indicator for optimizing the performance of IGCT converters. Therefore, low-THD patterns like the level-shifted carrier and Optimized Pulse Patterns are proposed. It is explored that a smart and instantaneous pattern distribution is a key factor to ensure a robust modulator design. Compared to the standard interleaving concept, the proposed modulation schemes allow a power capability increase up to 40%. Meanwhile, the current THD is reduced from 11% to 4 -7%. The concept is implemented and experimentally validated up to 30 MVA on an industrial IGCT converter. I.0093-9994 (c)
