3300V 1MVA H-브릿지 멀티 레벨 인버터 개발 = Development or 3300V 1MVA Multilevel Inverter using Cascaded H-Bridge Cell

다국어 초록 (Multilingual Abstract)

Multilevel power conversion technology has received increasing attention recently for high power applications. The converters with the technology are suitable for high voltage and high power applications due to their ability to synthesize waveforms with better harmonic spectrum and apply for the high voltage equipment with a limited voltage rating of device. In the family of multilevel inverters, the topologies based on cascaded H-bridges are particularly attractive because of their modularity and simplicity of control. <br/>
This paper presents multilevel inverter with cascaded H-bridge for large-power motor drives. The main features of this drive 1) reduce harmonic 1n]ection; 2) can generate near-sinusoidal voltages, 3) have almost no common-mode voltage, 4) are low dv/dt at output voltage; 5)do not generate significant over-voltage on motor terminal;<br/>
The topology of the developed product is presented and the feasibility study of the inverter on 3300V IMV A 7-level H-bridge type was carried out with experiments.<br/>
