A Simplified Space Vector Modulation for Four-Level Nested Neutral-Point Clamped Inverters With Complete Control of Flying-Capacitor Voltages
Abstract
Four-level nested neutral-point clamped (NNPC) inverters experience severe voltage balancing problems under low output-frequency conditions when the conventional four-level space vector modulation (4L-SVM) technique is applied, which limits their wider application. In order to get a complete control of the flying-capacitor voltages, and to alleviate the calculation burden of conventional 4L-SVM, a simplified but effective 4L-SVM technique along …
