Line-to-line Voltage Space Vector Modulation for Neutral-point Clamped Multi-level Converter with DC-link Capacitor Voltage Balancing Using Redundant Vectors

“…This solution generates new converter topologies known as multi-level converters [1][2][3]. These converters are used with increasing frequency in industry and research in electronic power conversion for high-power applications [1][2][3][4][5]. There are several advantages of multi-level inverters, including improved waveform quality, better output waveforms that reduce output filters and use of passive components, and low switching frequency that offers high efficiency.…”

“…The output voltage waveform of a multi-level inverter is composed of intermediary voltage levels, which are obtained from capacitor voltage sources, allowing use of a high DC bus and supplying higher power [1,2]; moreover, the various DC capacitor connections of the DC bus allow the use of many low power sources. The most popular multi-level inverter topologies are the neutralpoint clamped (NPC) converter, diode-clamped inverter (DCI), flying capacitor multi-level inverter (FCMI), cascaded multicell with separate DC sources (SDCS), and modular multilevel converter (MMC) [1][2][3][4][5][6][7]. The disadvantage of the DCI and NPC converter is the imbalance of the DC voltage capacitors.…”
