Motor Stator Insulation Stress Due to Multilevel Inverter Voltage Output Levels and Power Quality
Multilevel Inverters (MLIs) are widely sought after in medium-voltage applications like electric ships, electric aircraft, and renewable energy integration due to excellent advantages like lower device stress, better power quality, and modularity.However, non-sinusoidal excitations from MLIs pose a serious problem to motor-insulation and lead to th
