摘要： The rectifier includes a rectification MOSFET; a comparator having the non-inverted input terminal connected to a drain of the rectification MOSFET and the inverted input terminal connected to a source of the rectification MOSFET, and the control circuit controlling ON and OFF of the rectification MOSFET by an output of the comparator. The control circuit includes the shutoff MOSFET for performing shutoff between the drain of the rectification MOSFET and the non-inverted input terminal of the comparator and the shutoff control circuit performing electrical shutoff between the drain of the rectification MOSFET and the non-inverted input terminal of the comparator by turning off the shutoff MOSFET when a voltage of the drain of the rectification MOSFET is equal to or higher than a first predetermined voltage.

摘要： An electric generator may include a housing having a housing casing running around in a circumferential direction and front and rear side walls, a radially outer stator rotatably arranged on the housing about an axis of rotation, and a radially inner rotor arranged on the housing in a rotationally fixed manner. The generator may also have an axially outer impeller wheel arranged on an outer side of the front side wall and arranged in a rotationally fixed fashion on the rotor. The generator may further have a primary air inlet having inlet openings formed in the rear side wall, a secondary air inlet having secondary inlet openings formed in the housing casing, an air outlet having a plurality of outlet openings formed in the front side wall, a primary air path from the primary air inlet to the air outlet, and a secondary air path from the secondary air inlet to the air outlet. During operation, the impeller wheel may rotate with the rotor and generate a partial vacuum that generates a primary air flow, which enters the primary air inlet, follows the primary air path, and exits through the air outlet, and a secondary air flow, which enters through the secondary air inlet, follows the secondary air path, and exits through the air outlet.

摘要： A method is disclosed for generating and distributing electric power for localized use. The method entails providing an enclosed building having an air conditioning and ventilation unit for supplying cooled air within the building, the unit including a closed loop circuit configured to operate a closed loop refrigeration cycle, including a compressor operable to compress a working fluid of the closed loop circuit. The method further includes engaging an internal combustion engine with the compressor and operating the internal combustion engine to drive the compressor, thereby transferring energy to the refrigeration cycle. The method may also involve engaging an electric motor with the compressor and operating the electric motor to drive the compressor, thereby transferring energy to the refrigeration cycle.

摘要： A reluctance generator includes a circular stator made by silicon steel sheets and amorphous metal, first and second exciting coils, first and second outputting coils, and a rotator disposed in the stator. The stator includes four projecting poles. Two opposite ones and the other two opposite ones of the projecting poles are respectively formed with first and second teeth at distal ends thereof. The first exciting coil, the first outputting coil, the second exciting coil and the second outputting coil are in sequence and each wound around the stator between respective two adjacent ones of the projecting poles. When the rotator rotates, the first and second teeth are alternately aligned with third teeth that surround the rotator.

摘要： In accordance with one embodiment, a machine for generating electrical energy comprises a housing and a shaft rotatable with respect to the housing. An impeller has blades for rotation with the shaft in response to receipt of material from a chute. A first generator assembly comprises first stator windings associated with the housing and a first magnet affixed to the shaft, such that if the impeller rotates an electromagnetic signal energizes the first stator windings based on the flow of material through the chute.

摘要： An electrical machine with a rotor or the stator including a plurality of discrete field modules, and the other one of the rotor and the stator including a plurality of armature coils connected to different power converters. Each field module includes one or more field coils which can be activated independent of the field coils of the neighbouring field modules. When at least one of the field coils is inactivated, e.g. because of a defect, each of the power converters is allowing less power to pass through when an armature coil connected to it is moving over an inactivated field coil, and more power to pass through when the armature coil connected to it is moving over an activated field coil.
