Abstract: An electric power generation system may be constructed of multiple similar generator modules arranged between a rotor and a stator. The rotor may be coupled to and/or integrated with a turbine that is configured to rotate in the presence of a fluid stream such as wind or water. Each generator module may have a rotor portion configured to generate a magnetic field having at least one characteristic that changes with respect to the rotational speed of the rotor. Each generator module may further have a stator portion configured to generate an alternating electric current responsive to the magnetic field. The generated electric current may be controlled by the stator portion of the generator module in order to magnetically control the rotational speed of the rotor and the turbine. Separation between the rotor and stator portions of the generator module may be magnetically maintained.

Abstract: A magnetic braking system for inhibiting excessive motion between a float and a column intended to be placed in a body of water; with the float and column moving relative to each other as a function of the waves present in the body of water. The braking system includes a permanent magnetic assembly (PMA) mounted on, and attached to, one of the float and column and a coil assembly (or a conductive plate) mounted on, and attached to, the other one of the float and column. The braking system is mounted such that motion between the float and the column is inhibited when the displacement of the float relative to the column exceeds a predetermined operating range.

Abstract: A load adaptive linear electrical generator system is provided for generating DC electrical power. The electrical generation system includes one or more power generation modules which will be selectively turned on or off and additively contribute power depending on the DC power demand. Each power generating module includes a pair of linear electrical generators connected to respective ones of a pair of internal combustion piston based power assemblies. The piston in the internal combustion assembly is connected to a magnet in the linear electrical generator. The piston/magnet assembly oscillates in a simple harmonic motion at a frequency dependent on a power load of the electrical generator. A stroke limiter constrains the piston/magnet assembly motion to preset limits.

Abstract: In some examples, an alternator control device includes interface configured to receive a voltage signal from an engine control device, pull-down circuitry, and a switch electrically connected between the interface and the pull-down circuitry. The alternator control device further includes processing circuitry configured to determine that the voltage signal is higher than a threshold voltage level and to activate the switch to electrically connect the interface to the pull-down circuitry in response to determining that the voltage signal is higher than the threshold voltage level. The processing circuitry is further configured to determine that, at least a threshold time duration after activating the switch, the voltage signal is higher than the threshold voltage level and to refrain from delivering the excitation current based on determining that, at least the threshold time duration after activating the switch, the voltage signal is higher than a threshold voltage level.
