Abstract
We propose a simple and an inexpensive wind power generating system in this paper. Existing wind power generating systems are mostly of large capacity (over 100kW) and high-priced (about 700kyen/kW). We adopt compact permanent magnet type synchronous generator, which doesn't need exciting current, and step-up/down buck-boost chopper to wind power generating system of a few kW output without position or speed sensor. In addition, we employ inexpensive rectifier circuit using Diode Bridge instead of AC/DC converter with PWM method. Using this method we achieve a simple and inexpensive wind power generating system.
