Wide range modulation indexes featuring carrier-based PWM stepped waveform for half-bridge modular multilevel converters

This paper presents simulation results of the influence of wide range modulation index values ( a m ) in carrier-based PWM strategy for application in generating the stepped waveform. The waveform is tested for application in single-phase half-bridge modular multilevel converters (MMCs) topology. Th...
