Abstract

This paper presents a novel dual mode six- switch five-level boost-ANPC inverter (5L-DM-ABNPC) topology with wide input voltage range (400 V - 800 V). It consists of one flying-capacitor and six semiconductor switches forming a similar structure to that of conventional 5L-ANPC or 5L-ABNPC inverter. Depending on the magnitude of the input voltage, the converter can operate in buck or boost mode to produce the same ac voltage out. Further, the number and the size of the active and passive components are also reduced with simple PWM control. Consequently, this make the overall system appealing for various industrial applications. The analysis shows that the proposed topology is suitable for wide range of power conversion applications (for example, rolling mills, fans, pumps, marine appliances, mining, tractions, and most prominently grid-connected renewable energy systems). Simulation and experimental prove the concept of the proposed inverter. The principle of operation and theoretical analysis supported by key simulation and preliminary experimental waveforms are presented.
