description	Use when working on Simulink or Simscape Electrical multilevel converter models beyond the populated three-phase inverter notes, including MMC, cascaded H-bridge, flying-capacitor converters, capacitor balancing, and arm-energy control.

Multilevel And MMC

Status

Stub. Use this file only to recognize broader multilevel/MMC scope and choose evidence to collect. The active inverter subskill covers only its populated T-type/NPC three-level SVPWM notes.

Scope

• modular multilevel converters
• cascaded H-bridge and flying-capacitor converters
• capacitor voltage balancing
• arm energy and circulating-current control
• multilevel modulation and switching-state validation beyond the existing three-level inverter table

Evidence To Collect

• topology, submodule count, modulation path, balancing strategy, and arm/control hierarchy
• capacitor voltages, arm currents, circulating current, arm energy, and switching-state signals
• startup, balancing, step response, or disturbance window used for validation
• state encoding, bypass/insert assumptions, and measurement polarity

Promote When

Promote only after adding representative MMC or broader multilevel workflows, validated modulation references, and checks for submodule states, balancing, and arm energy.
