A Single-Carrier-Based Pulse-Width Modulation Template for Cascaded H-Bridge Multilevel Inverters
IEEE Access, 2021 Multiplicity of the triangular carrier signals is a criterion for the extension of sinusoidal pulse-width modulation, SPWM, to a number of output voltage levels per phase-leg in cascaded H-bridge (CHB) multilevel inverter (MLI).

Modelling approach for multi‐carrier‐based pulse‐width modulation techniques utilised in asymmetrical cascaded H‐bridge inverters [PDF]
IET Power Electronics, 2019 The increasing use of medium‐voltage drives and high‐power equipment requires a detailed study on the switching method and topology of multi‐level inverters. Asymmetric cascaded H‐bridge topologies that have unequal input dc voltages with different devices in various parts of the cascaded H‐bridge inverter (CHB) are representative of significant ...
