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 ...
