Modulation indices embedded carrier-based PWM generation for modular multilevel converter
The fundamental component (50Hz) in the output voltage of a single-phase modular multilevel converter (MMC) can be diverted by varying of the value of modulation index (Mi). However, this changing affects on the value of the total harmonic distortion of the output voltage (THDv) and output curre...

| Summary: | The fundamental component (50Hz) in the output
voltage of a single-phase modular multilevel converter (MMC)
can be diverted by varying of the value of modulation index (Mi).
However, this changing affects on the value of the total harmonic
distortion of the output voltage (THDv) and output current
(THDi). Moreover, the variableness of modulation index can be
differentiated to be linear region and over-modulation region to
consider the correlation of modulation indices and fundamental
component, and THD. Each region has a different effect on
THDv and THDi. To facilitate, this paper demonstrations the
results of carrier-based PWM strategy simulation in a singlephase
7-level MMC with a single-phase induction motor as a load
to study the behavior of THDv and THDi when the modulation
index value is changed. |
