摘要： A device for harvesting energy from a power line carrying AC current including: a transformer having a core with separate first and second sections, the core being formed of ceramic material or layered nickel alloy tape; a first secondary winding wound around the first section of the core; a second secondary winding wound around the second section of the core; a first DC core-flux control winding wound around the first section of the core; and a second DC core-flux control winding wound around the second section of the core; wherein the core is configured to be in operative communication with a magnetic field radiated from the power line, such that an AC voltage is generated in the first and second secondary windings, and the maximum AC voltage produced by the first and second secondary windings is limited by the first and second DC core-flux control windings.

摘要： An apparatus for controlling electrical characteristics in an alternating current system includes a first level of magnetic amplifiers which are responsive to a primary direct current control signal. The magnetic amplifiers provide secondary control signals in response to the primary control signal. The secondary control signals control a second level which includes a magnetic amplifier having gate windings to which the alternating current to be controlled is connected. Depending upon the nature of the primary control signal, the current magnitude or voltage magnitude of the alternating current can be controlled, both in relation to other alternating currents and in relation to a predetermined current or voltage magnitude.

摘要： An electrical power distribution network includes: a plurality of electrical power control apparatuses, each of which include one or more signal conversion components receiving electrical power in the form of a first signal and generating a corresponding second signal, a controller that controls operation of the signal conversion components, electrical power generation components acting as sources of electrical power to at least some of the electrical power control apparatuses, and electrical power consumption components acting as sinks of electrical power from at least some of the electrical power control apparatuses. The electrical power control apparatuses operate autonomously but are interconnected so that the electrical power control apparatuses collectively maintain the voltages and frequencies of electrical power signals flowing through the electrical power distribution network at target values to compensate for variations in the sinks and/or sources of electrical power.

摘要： For transmitting voltage and current between a source and a load, a magnetic amplifier with a power winding connectable with the source and the load and with at least one control winding is provided, and current and voltage difference between the source and the load are controlled by applying a portion of a rectified source voltage to the at least one control winding of the magnetic amplifier, and applying a portion of a rectified load voltage to the at least one control winding of the magnetic amplifier to prevent the current from exceeding a level which can endanger the source and/or the load and to minimize the voltage difference between the source and the load.

摘要： An apparatus and method is disclosed for an improved variable impedance transformer for controlling the power from an alternating input power source to a load in accordance with a direct current control signal. The invention comprises a DC control winding simultaneously wound about a plurality of saturable reactor cores and a plurality of AC power input windings simultaneously wound about a power core and each of the saturable reactor cores. A power output winding is wound about the power core for delivering power to the load. A low impedance equalizing winding is wound about the saturable reactor cores for shunting any resultant alternating voltage as a result of physical variations between the saturable reactor cores.
