Abstract

Three controls, three variable gear assemblies, a hatch, and a variable torque and power generator (VT&PG), may be used independently and together to provide constant frequency and voltage output power and to increase the amount of output power generated with the same input water flow or wind speed. A three variable spur/helical gear assembly of sun and planetary gear sets is a mechanical three variable control and referred to herein as a Transgear™ gear assembly, simply Transgear. A hatch wraps around a waterwheel and may control the amount of water inlet to the system by opening and closing and may be controlled by Transgears and a VT&PG. Two Transgears may comprise a constant speed motor control and produce required frequency and voltage and be reduced in part count and complexity. The VT&PG of a marine hydrokinetic or wind power generator may be used as a low torque generator and a high power-rated generator in these applications and may generate more electric power than a conventional fixed power generator (the rotor axially aligned to overlap the stator in a conventional manner) over a wider input range.
