Modeling and Simulation of Modular Multilevel Converter

Implementation Plan:

Scenario 1: Using Five‑Level MMC with Motor

Step 1: Initially, we will construct the five-level MMC with DTC control of a three‑phase induction motor model in Simulink with a grid rectifier-inverter.

Step 2: Next, we implement control strategies including DTC  lookup table and PWM control logic.

Step 3: Next, we simulate the model and  collect waveforms such as voltage, current, torque, flux, and harmonic data.

Step 4: Then, we analyze the DTC control by detecting mapping torque and flux errors based on collected data.

Step 5: Finally, we evaluate performance metrics for the following:

Scenario 2: Using Dual MMC with Common DC Link

Step 1: Initially, we will construct the five-level MMC with two three‑phase MMC unit models in Simulink with a grid rectifier-inverter where both MMC operate as a rectifier connected to DC link, enabling active and reactive power control.

Step 2: Next, we implement control strategies using PWM control logic.

Step 3: Next, we simulate the model and  collect waveforms such as voltage, current, torque, flux, and harmonic data.

Step 4: Then, we analyze the control logic by detecting mapping torque and flux errors based on collected data.

Step 5: Finally, we evaluate performance metrics for the following:

Scenario 3: Using MMC Active Filter for Harmonics

Step 1: Initially, we will construct the five-level MMC model in Simulink with grid rectifier-inverter, and harmonic mitigation where the MMC acts as an active filter to reduce the harmonic content through current injection.

Step 2: Next, we implement control strategies using PWM control logic.

Step 3: Next, we simulate the model and  collect waveforms such as voltage, current, torque, flux, and harmonic data.

Step 4: Then, we analyze the control logic by detecting mapping torque and flux errors based on collected data.

Step 5: Finally, we evaluate performance metrics for the following:

Note:

1) If the proposed plan does not fully align with your requirements, please provide all necessary details—including steps, parameters, models, and expected outcomes—in advance. Kindly ensure that any missing configurations or specifications are clearly outlined in the plan before confirming.

2) If there’s no built-in solution for what the project needs, we can always turn to reference models, customize our own, different math models or write the code ourselves to fulfil the process.

3) If the plan satisfies your requirement, Please confirm with us.

4) Project based on Simulation only.
