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： A power supply system including a distribution transformer connected to a supply grid and supplying a plurality of remote electric loads over a supply network, measuring means for measuring total power transferred between the grid and loads through the transformer, and control signal generation means to signal some of the loads to switch off in response to determining that the measured power transfer exceeds a maximum set point in order to limit the peak power transferred through the transformer.

摘要： The present application relates to the detection of moving vehicles and other objects, in particular though not exclusively for the application of switching stationary charging pads for moving electric vehicle charging. There is provided an electric vehicle detecting apparatus for switching a charging pad for charging a vehicle transmitting a locating signal, the apparatus comprising two sensors separated in the direction of travel of the vehicle, and a detector arranged to detect the vehicle by comparing the locating signals received by each of the two sensors.

摘要： An inductive power transfer (IPT) pick-up circuit has a full-wave rectifier (D1-D4) coupled to a resonant circuit (L1 C1) and adapted to rectify an AC current received from the resonant circuit. A pair of inductors (L2 L3) are provided, being arranged to couple the rectifier to an output (VLoad) of the pick-up circuit and alternately store and release energy to the output.

摘要： An IPT system magnetic flux pad includes two substantially planar coils (17) in close proximity to each other above a magnetically permeable core (14). The coils (17) each define a pole area (11, 12) and the distance between one or more adjacent turns of the coils (17) located in a region between the pole areas (11, 12) being different from the distance between one or more adjacent turns of the coils (17) located outside the region between the pole areas (11, 12).

摘要： A circuit for energizing a magnetic flux coupling apparatus has a pick-up coil for receiving power inductively, a storage capacitor for storing energy from the received power, and an inverter for supplying electrical energy from the storage capacitor to the magnetic flux coupling apparatus. The circuit allows power transfer to a load to be supplied by the flux coupling apparatus to exceed the power received from the pick-up.

摘要： A roadway powered electric vehicle system includes a power supply (101) which makes power available inductively to one or more modules (111) provided in or under a roadway. Modules (111) make a magnetic field selectively available to one or more vehicles travelling over the roadway corresponding to the location of the vehicle. The presence or strength of the magnetic field provided on the roadway may be dependent upon the vehicle type or category.
