Abstract: An apparatus and method for extracting a maximum amount of power from a water source includes: a hydroturbine assembly including a shaft; a turbo generator connected to the shaft of the hydroturbine assembly; a frequency sensor for sensing a frequency output by the generator associated with a turbine speed of the hydroturbine; a power converter that converts the electrical output of the turbo generator to a predetermined power value; a power sensor for sensing an output power of the power converter; a maximum power controller that maximizes a power output of the power converter based on: (a) the frequency of the electrical output of the turbo generator sensed by the frequency sensor; and (b) the output power of the power converter sensed by the power sensor; and an energy reservoir for receiving the output of the power converter; wherein the maximum power controller calculates a maximum power output of the power converter.

Abstract: The present invention is an assembly for pumping liquid at a constant, preselected outlet pressure, and includes an engine connected to a variable displacement hydraulic pump driven by the engine. A fixed displacement hydraulic motor driven by the variable displacement hydraulic pump includes a motor speed transducer. The fixed displacement hydraulic motor drives a liquid pump and contains a liquid outlet pressure transducer. A controller device modulates the output of the variable displacement hydraulic pump. The controller device is in communication with the liquid pump outlet pressure transducer, and with the fixed displacement hydraulic motor speed transducer. The controller thereby modulates the hydraulic output of the variable displacement hydraulic pump to maintain a constant, preselected liquid pump outlet pressure that is independent of engine speed and within the fixed displacement hydraulic motor speed maximum.

Abstract: In one embodiment, a power processor which operates in three modes: an inverter mode wherein power is delivered from a battery to an AC power grid or load; a battery charger mode wherein the battery is charged by a generator; and a parallel mode wherein the generator supplies power to the AC power grid or load in parallel with the battery. In the parallel mode, the system adapts to arbitrary non-linear loads. The power processor may operate on a per-phase basis wherein the load may be synthetically transferred from one phase to another by way of a bumpless transfer which causes no interruption of power to the load when transferring energy sources. Voltage transients and frequency transients delivered to the load when switching between the generator and battery sources are minimized, thereby providing an uninterruptible power supply.
