Modeling and Simulink of Single Phase Five Level Multilevel Inverter With Rated Power Fault Tolerant
Implementation Plan:
Scenario 1: (With No Faults)
Step 1: Initially, we constructed a single-phase five-level multilevel inverter model .
Step 2: Next, we simulate and collect data such as load voltage, load current, switch currents, THD and switching states.
Step 3: Next, we analyze the inverter’s DC-source fluctuation handling by modifying carrier heights using the voltage stress equations and observing THD changes under voltage conditions.
Step 4: Next, we perform loss analysis (switching loss, conduction loss, total power loss) and efficiency using the Loss Model–Based Power Analysis Method based on collected data.
Step 5: Finally, we plot performance metrics for the following:
5.1: Time (s) vs. load voltage (V)
5.2: Time (s) vs. load current (A)
5.3: Time (s) vs. THD (%)
5.4: Time (s) vs. Power Loss (W)
Scenario 2: (With Fault)
Step 1: Initially, we constructed a single-phase five-level multilevel inverter model with single-switch fault through a level-shift PWM fault tolerant mechanism.
Step 2: Next, we simulate and collect data such as load voltage, load current, switch currents, THD, switching states, and fault-detection timings.
Step 3: Next, we apply the post-fault reconfiguration strategy to restore missing voltage levels and maintain rated power based on collected data.
Step 4: Next, we analyze the inverter’s DC-source fluctuation handling by modifying carrier heights using the voltage stress equations and observing THD changes under voltage conditions.
Step 5: Next, we perform loss analysis (switching loss, conduction loss, total power loss) and efficiency using the Loss Model–Based Power Analysis Method based on collected data.
Step 6: Finally, we plot performance metrics for the following:
6.1: Time (s) vs. load voltage (V)
6.2: Time (s) vs. load current (A)
6.3: Time (s) vs. THD (%)
6.4: Time (s) vs. Power Loss (W)

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.
