Abstract
The development of open-source power electronics platforms plays an instrumental role in accelerating microgrid deployment, electric vehicle (EV) integration, and educational access to embedded power electronic converters. This thesis presents the design, implementation, and validation of the Atinverter V2, an open-source DC to AC inverter intended for low power EV microgrid applications and educational settings. The Atinverter V2 integrates various hardware and software subsystems centered around the ATMEGA328P microcontroller, enabling PWM-based sinusoidal power inversion, DC/AC voltage and current sensing, and embedded control features. Software development leverages a C++ object-oriented library and multiple Arduino-based modules to facilitate modular and scalable operation. A dedicated GitHub repository provides full access to the schematic and layout files, firmware, simulation tools, and a Jekyll-based website with comprehensive documentation. This promotes transparency, replicability, and community driven development for the open-source community. Experimental results confirm functional PWM generation, AC waveform operation, and reliable DC/AC sensing performance. These findings establish the Atinverter as a practical and educational tool for prototyping microgrid-ready EV platforms and fostering hands-on learning in power electronics.
