Isolation amplifiers (iso-amps), working in conjunction with shunt resistors, provide accurate current measurements in power converters even in the presence of high switching noise. When used with a resistive divider, they work as precision voltage sensors. The current and voltage information is required by the controller for calculation and effective control to achieve optimum conversion efficiency in typical small wind power systems. Featured with high common mode noise rejection, high isolation voltage, built-in safety insulation and very small footprint, miniature iso-amps provide a solution for small wind power turbines.

As one of the most promising alternative energy resources, wind power will continue to grow fast, despite the financial crisis and economy recession, at an annual rate of 22.4 percent average for the next five years. Large wind power farms are expanding to offshore deep water regions, such as the 25MW Arklow Bank Wind Park in the Irish Sea, and the Cape Wind, America's first offshore wind farm, coming with 420MW capacity.

Despite the attention given to large multi-megawatt wind turbines, which are projected to continue growing both in size and number of installations, most of the opportunities for power inverter manufacturers are in the small wind turbine market (View the PDF document for more information.
