A Novel Vector-Based Pulse-Width Modulation for Cascaded H-Bridge Multilevel Inverters [PDF]
Journal of Operation and Automation in Power Engineering, 2023 The conventional space vector pulse-width modulation (SVPWM) for cascaded H-bridge inverters (CHBIs) has problems of computational complexity and memory requirements. Operation in overmodulation mode is the other reason for the complexity in SVPWM.
