PENNINGTON, N.J., June 22, 2005 (PRIMEZONE) -- WorldWater & Power Corporation (OTCBB:WWAT), maker of high-horsepower solar energy systems, today filed an application with the U.S. Patent and Trademark Office for a Maximum Power Point Speed Control, a method and apparatus that performs maximum power tracking of motor speed. The present invention relates generally to the operation of AC motors or similar loads with AC motor drives that convert power from a DC source (such as sun power) to AC, and more particularly to operation of the motor at maximum power as the power from the DC source varies.
A particular application is to solar powered systems and water pumps. A solar powered water pumping system typically has three primary components: the solar array, made of photovoltaic (PV) modules; a converter (inverter or motor drive) which converts the DC from the PV array to AC; and an AC motor (pump). The motor typically runs at a particular frequency (speed), e.g. 60 Hz. The converter will usually be set to provide AC power at that particular frequency. The motor will run at a speed equal to the AC frequency. The WorldWater & Power development replaces hardware with software enabling the motor to change speed in order to operate optimally with the available power from the sun.
