Modular Multi-level Converter (MMC) in High-voltage direct
To demonstrate this, MMC model performance is shown in an HVDC (High-voltage direct current) transmission application, one of the main application areas for MMCs. The model contains six
Modular Multilevel Converter-High Voltage Direct Current
For MMC-HVDC we use a sorting algorithm, which switches submodules in a particular order to equalise their capacitor voltages, instead of using PWM. Figure: Full average equivalent.
Modular Multilevel Converter
The modular multilevel converter (MMC) is a reasonably young inverter technology with a promising future in medium voltage DC (MVdc) systems, such as large wind turbines in the DC
What are Modular Multilevel Converters?
DC to AC Conversion (Inversion): When converting DC to AC (inverter mode), a DC voltage is applied to the converter''s DC terminals.

DC to AC Conversion (Inversion): When converting DC to AC (inverter mode), a DC voltage is applied to the converter''s DC terminals. The MMC uses the submodules to generate
Modular multilevel converter (MMC)
Modular Multilevel Converters (MMCs) are a type of power electronic converter used for medium- and high- voltage direct current convertion, consisting of a multitude (up to several hundreds)
MMC inverters, or Modular Multilevel Converters
By controlling the switching of the sub-modules, the MMC can generate a near-sinusoidal output voltage with a very high number of voltage levels. This results in reduced
Multi-level converter
A multi-level converter (MLC) or (multi-level inverter) is a method of generating high-voltage wave-forms from lower-voltage components. MLC origins go back over a hundred years, when in the
