| Abstract |
An IGBT-based three-phase inverter system is designed for microgrid applications and sustainable industrial operations. This inverter converts DC power into three-phase AC, ensuring reliable electricity conversion. Instead of MOSFETs, Insulated Gate Bipolar Transistors (IGBTs) are used in this system. The proposed method generates 223V AC square waves for each phase from a 12V DC battery. This conversion process necessitates precise switching of three IGBT power stages. PWM signals from an Arduino Uno R3 control the switching of IGBTs, ensuring accurate and seamless phase conversion. Each of the three single-phase connections includes six IGBT components, totaling eighteen, enabling independent operation. The Arduino Uno R3 generates PWM signals with a 120-degree phase shift to ensure synchronization. Step-up transformers at the outputs of the IGBTs boost the signal, and a 60W incandescent lamp is used in each load testing phase to assess system performance. Experimental results demonstrate that the three-phase output meets operational requirements, delivering 386.25V and 0.58A. The electronic circuit design and simulation using Proteus 8.9 Professional ensure the reliability of the system. Arduino IDE is employed for programming Arduino Uno, facilitating easy integration and control. Practical testing validates the system's performance under real-world conditions, confirming its suitability for deployment in microgrid and industrial applications requiring sustainable power conversion solutions |
