Vertical Axis Wind Turbine Projects with Integrated Inverter Technology


As the global demand for renewable energy sources intensifies, vertical axis wind turbines (VAWTs) have come into the spotlight. Unlike the traditional horizontal axis wind turbines, VAWTs offer a unique set of advantages suitable for various environments. This article dives into the specifics of setting up a vertical axis wind turbine project integrated with an inverter.

Vertical Axis vs. Horizontal Axis

While horizontal axis wind mills have been the conventional choice for harvesting wind energy, vertical axis wind turbines bring a different set of advantages. One critical benefit of VAWTs is the ability to capture wind from all directions without the need for reorientation.

Working Principle

The vertical axis wind turbine working principle revolves around the conversion of wind energy into mechanical energy through its blades. The blades’ rotation powers a DC motor, which subsequently charges a 12V battery. The energy stored is then converted back to AC through an inverter, making it usable for various applications.

Hardware Components

  • Atmega Microcontroller: The brain of the operation
  • Windmill: To capture the wind energy
  • LCD Display: To show real-time energy metrics
  • Transformers, Transistors, Resistors, etc.: These are the supporting elements that ensure seamless energy transformation and storage.

Software Specifications

The system employs the Arduino Compiler and is programmed using the C language. This flexibility allows for easy debugging and updates.

Inverter Technology

The inverter plays a critical role in converting the DC output into AC. It uses MOSFET switches regulated by the Atmega microcontroller for efficient conversion.

Block Diagram & Types of Vertical Axis Wind Turbine

Incorporating various types of vertical axis wind turbines can be beneficial depending on the application. Savonius, Darrieus, and Giromill are common types. The vertical axis wind turbine diagram and wind energy block diagram provide a clear visual representation of the system architecture.


Vertical axis wind turbines integrated with inverters represent a significant leap in renewable energy technology. From their working principle to the types of vertical axis wind turbines, understanding each component can lead to more efficient and sustainable energy solutions.
