This thesis presents a comprehensive investigation into the implementation of a Three-Level T-type Neutral Point Clamped (TNPC) inverter, a pivotal component in modern power electronic systems. The research extensively explores various modulation techniques that are crucial for optimizing the performance of the inverter, including Level Shifted Sinusoidal Pulse Width Modulation (LS-SPWM), Phase Shifted Sinusoidal Pulse Width Modulation (PS-SPWM), and Space Vector Pulse Width Modulation (SVPWM).

To enhance the control of the inverter, this study employs several advanced current control strategies, namely Field Oriented Control (FOC), and Field Weakening Control (FWC). These strategies are designed to maximize the efficiency and responsiveness of the system under varying operational conditions.

For effective neutral point voltage management, the model integrates Zero Sequence Control across all carrier-based modulation techniques and Active Time Balancing specifically for time-based SVPWM. This dual approach ensures stability in the neutral point voltage, thereby improving overall system reliability.

Furthermore, the inverter model is complemented by realistic representations of a battery model and a motor model, which facilitate the simulation of practical applications. This holistic approach not only underscores the versatility of the TNPC inverter but also contributes to a deeper understanding of its operation in real-world scenarios.

The findings of this research aim to provide valuable insights into the design and control of TNPC inverters, paving the way for future advancements in power electronics and their applications in various industries.
