単相マルチレベルインバータのスイッチング素子数削減と波形改善の一方式

抄録

This paper focuses on the circuit capable of reducing the number of switching elements (six-switch inverter) in comparison to a common multi-level neutral point clamped inverter. Waveform improvement is carried out by increasing the number of levels of the output voltage. This is possible by providing the ratio of the input voltage. The simulated and experimental results demonstrate the effectiveness of the six-switch inverter.
