摘要： Apparatus for providing effective amounts of high-frequency AC power to a long primary trackway (1102), used for inductive power transfer includes transconductance-pi filters (1105) for deliberate mismatching; resulting in independence of current flow and track impedance. These cause the source (1101) to appear as a voltage source and the trackway to appear as a low reactance. Shorting the output (1106) cuts the connected trackway from power without harm. The filter can cause a voltage step-up so driving a longer track. Track termination apparatus is disclosed that acts as a short circuit at only the operating frequency while terminating the track at its characteristic impedance otherwise. Half-bridge and full-bridge power supplies (1101) are described for providing effective amounts of high-frequency AC power to a long primary trackway used for inductive power transfer.

摘要： Loosely coupled inductive power for charging batteries is rectified from a first power pickup winding and the resulting current source is connected to a battery unit. Each current source is controlled by shorting a second resonant winding. Battery banks may be charged using multiple isolated position-tolerant pickups independently controlled according to the condition of the connected battery unit and by overall commands communicated over an isolated link. The battery unit may be a single cell. In a self-stabilizing bank or monoblock a primary inductive conductor is energized using all the cells, individual cells are separately monitored by control means and any below-average cell can be individually charged from the inductive conductor, thus correcting between-cell variations. The charge in all cells within a bank can be held within 30% to 70% of full charge and prevented from drifting towards full or empty during repetitive charge and discharge times.

摘要： A circuit (700) for an electric fence energizer (examples are 6 or 24 Joule versions) which synthesizes a pulse having a raised cosine waveform at a first or bus voltage uses a ferrite-cored output transformer (701) to multiply the voltage of the pulse to the required level. A raised cosine waveform has a low harmonic content and little filtering of high-power pulses is required in order to minimize electromagnetic emissions. On closure of a switch (707) in series with an inductor (705) a first capacitor bank (703) commences charging a second smaller capacitor bank (704) in parallel with the output primary and after the peak of the pulse any remaining charge is dissipated in a resistor (708) with the aid of a saturable inductor (702), acting as a switch. The saturable inductor may be the output transformer itself for lower output energizers. The output exhibits little or any reversal of polarity when matched to its load. The circuit may also be useful for applications such as strobe flashers in aircraft.

摘要： The present invention relates to a current multiplier primarily in the field of power conversion. The invention relates to a controlled current multiplier with a resonant winding to assist with, for example, power conversion. In particular, but not solely, the invention may broadly consist in a current multiplier comprising: a primary winding associated with a power source; a secondary winding associated with a load; a resonant winding associated with a capacitance; and a control means for controlling an output of the secondary winding to the load, the control means associated with the primary or resonant winding. This allows, for instance, control of the high current output to be placed on a low current winding.

摘要： A demand side electric power supply management system is disclosed. The system comprises an islanded power system having a point of coupling to a supply grid. The islanded power system supplies a plurality of electric loads, each of which is associated with a load controller to control the maximum power demanded by that load. A measuring means associated with the point of coupling measures the total power transfer between the grid and the islanded system, and a system controller monitors the measured power transfer relative to a set point and provides a control signal to a plurality of load controllers. Each load controller receives substantially the same control signal and determines the maximum power which the or each load associated with the load controller is allowed to draw from the islanded power system based on information contained in the control signal.

摘要： An inductive power transfer (IPT) control method is disclosed for controlling the output of an IPT pick-up. The invention involves selectively shunting first and second diodes of a diode bridge to selectively rectify an AC current input for supply to a load, or recirculate the AC current to a resonant circuit coupled to the input of the controller. By controlling the proportion of each positive-negative cycle of the AC input which is rectified/recirculated, the output is regulated. Also disclosed is an IPT controller adapted to perform the method, an IPT pick-up incorporating the IPT controller, and an IPT system incorporating at least one such IPT pick-up.
