The VIRYA-15 windmill is designed for use in western countries as well as in developing countries. The windmill is meant to be connected to a 380 V or 400 V, 3-phase grid. The windmill has a simple two bladed rotor with wooden blades. In the first instance it is chosen to use a direct drive permanent magnet (PM) generator but it might be that the generator is driven by an accelerating gear box. The 3-phase generator current is rectified and the generated power is feed in the grid by an inverter.
