SIMULATION MODEL ON CURRENT CONTROL OF A THREE-PHASE THREE-LEVEL INVERTER USING SVM TECHNIQUE

This project is suitable for final-year projects, M.Tech studies, and practical learning in power electronics and inverter control.
Space Vector Modulation (SVM) is an advanced and widely-used pulse-width modulation technique, especially advantageous for controlling three-phase inverters. When applied to a three-level inverter, SVM enhances the performance of renewable energy systems, motor drives, and various power system controllers.

What Is a Three-Level Inverter?

A three-level inverter improves upon conventional two-level inverters by generating additional voltage levels, resulting in better waveform quality and reduced switching stress.

Advantages include:

• Reduced harmonic distortion

• Smoother output voltage and current

• Lower switching losses

• Improved efficiency in high-power applications

This model focuses on how SVM-based current control can be implemented on a three-phase three-level inverter for high-performance applications.

Key Features:

• Three-phase, three-level inverter topology modeled in MATLAB Simulink

• Space Vector Modulation (SVM)–based current control strategy

• Accurate current control ensuring stability and fast dynamic response

• Improved output waveform with reduced harmonics compared to two-level inverters

• Suitable for renewable energy systems such as solar/wind grid-tie inverters

• Applicable to motor drives and grid-connected converters

• Helps compare two-level vs. three-level inverter performance in terms of THD and waveform quality

After Payment Delivery:

• Complete MATLAB Simulink model .slx file - compatible with MATLAB R2022b or later

• Basic support for setup and simulation issues

• A readme file for step-by-step guide for simulation

• A license file 

Implementing current control using the SVM technique in a three-phase, three-level inverter significantly enhances output quality, control accuracy, and efficiency.
