Modeling & Simulation of Single stage MMC based isolated AC DC converter
Implementation Plan:
Step 1: Initially, we will construct the MMC-based isolated AC/DC megawatt charging system model with medium-frequency transformer and MV grid interface in Simulink.
Step 2: Next, we integrate transformer flux balancing and dc-bias mitigation methods to prevent magnetic core saturation into the MMC system.
Step 3: Next, we simulate the model and collect voltage, current, switching loss, harmonic distortion and transformer flux data.
Step 4: Then, we analyze the operating policies and modulation strategies to reduce switching frequency, improve waveform quality, and achieve soft switching using the collected data.
Step 5: Finally, we evaluate performance metrics for the following:
5.1: Time vs Voltage (V)
5.2: Time vs Current (A)
5.3: Time vs Transformer Flux (Wb)
5.4: Time vs THD (%)
5.5: Time vs Switching Frequency (Hz)
Software Requirements:
1. Development Tool: MATLAB R2023a/Simulink or above
2. Operating System: Windows-10 (64-bit) or above
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.
