Abstract

Nowadays the medium and high voltage large power AC-DC-AC converters are used in various industrial fields. The integrated gate commutated thyristor (IGCT) is applied to high power AC-DC-AC converter on a large scale due to its excellent characteristics. In this paper the investigation on IGCT-based five-level NPC/H-bridge high power converter is proposed. Each phase of the five-level NPC/H-bridge converter is composed of two IGCT-based three-level neutral point clamped (NPC) legs in an H-bridge form. The converter adopts modular design and the module of IGCT-based three-level NPC legs has been developed. One type of modulation scheme based on three-level SVPWM is introduced and the experiment result is showed in this paper.
