一种改进的基于四倍升压开关电容的九电平逆变器

This letter proposes an improved quadruple boosting nine-level (IQB9L) inverter with a reduced component count requiring ten switches, three diodes, and two capacitors for 9 L operation. The capacitors are self-voltage balanced using the series-parallel technique, ensuring sensorless operation. The devised structure exhibits the least conducting devices at each level resulting in reduced conductio...
