The invention relates to a regenerative energy system comprising a first energy producer and a second energy producer. The object of the invention is to improve the environmental compatibility of electrical island networks. There is disclosed a regenerative energy system comprising a first energy producer whose energy production is dependent on the weather and/or the position of the sun, wherein the first energy producer has a generator, by means of which electrical energy is produced, which is fed into an electrical network to which a plurality of consumers are connected, and a second energy producer which has a generator and an internal combustion engine connected thereto, wherein the second energy producer has a tank with fuel which when required can be fed to the internal combustion engine, wherein an installation is adapted to produce the fuel from renewable raw materials and the fuel production installation takes electrical energy for operation thereof from the first energy producer in particular when the first energy producer can produce more electrical energy than the consumers connected to the network consume and/or there is an energy demand from the network to the first energy producer system, which allows the feed of energy to a second energy producer.

A power supply (1) for a load in the form of a PCMCIA card (2) has an onboard GPRS class (10) module (not shown). The module, and therefore card (2), demands a load current iload that has an average value over time and periodic instantaneous peak values (ipeak) that are significantly higher than the average value. Power supply (1) includes a pair of input terminals (3) for connecting with a power source in the form of a regulated power supply (4) that is contained within a personal computer (not shown). Supply (4) supplies a source current iinput that is less than a predetermined current limit specified for the supply and which is less than the peak load current. A pair of output terminals (5) is electrically connected with terminals (3) and card (2). A supercapacitor device in the form of a single supercapacitor (6) is in parallel with terminals (3, 5) for allowing the load to be supplied the peak load current while maintaining the source current at less than the predetermined current limit.

The invention concerns a self-contained system for generating electricity comprising flywheel power storage. Said system comprises an assembly (1) comprising a heat engine (2), a mechanical speed regulator (34), a clutch (5), a flywheel (6) and a generator (42, 43). The assembly consisting of the clutch (5), the flywheel (6) and the generator (7) is positioned in a vacuum chamber (26) to reduce power losses. Said system is designed to be installed directly in buildings where power is used, for instance individual houses. It enables to eliminate electric power network connection.

A generator device provides a controlled electric output current to a load, and comprises a source of mechanical energy, a gear train connected to the source, a generator connected to the output of the gear train, and a control circuit connected to the output of the generator to control the output level thereof, the control circuit being such that the feedback generated by the control circuit alone is sufficient to prevent uncontrolled release of the energy in the power source.
摘要:
An inductive load driver comprising a DC-DC converter which has a coil (L) and a switch (Sw) in series with a power source (E) and a capacitor (C) provided in parallel with the switch (Sw). The DC-DC converter produces a high voltage by a procedure in which the switch (Sw) is closed to apply the power source voltage to the coil (L) and then the switch (Sw) is opened to transfer the magnetic energy stored in the coil (L) to the capacitor (C). Using a permanent magnet (Mg) a bias in the direction opposite to that of the magnetic flux induced by the current is applied to the magnetic core of the coil (L) so as to increase the magnetic energy stored in the coil (L). Thus a DC-DC converter circuit in which a capacitor is efficiently charged through a small-sized coil is realized, and an inductive load driver having a small size and a light weight is also realized.
