Embodiment Construction

[0064] Although the following description primarily relates to on-road and electric vehicle applications, those skilled in the art to which this invention pertains will appreciate that the subject matter is also broadly applicable to IPT systems, and may be used in applications such as material handling. Further information for practicing the present invention can be found in International Patent Publication WO2011 / 016736, the contents of which are incorporated herein by reference.

[0065] In one embodiment ( Figure 1A and 1B shown as an example in ), a series of power suppliers 101 are arranged in groups of two next to the road 100 and spaced about 200 meters apart. Each power supplier 101 is connected to a three-phase utility supplier at 50 / 60Hz 400 / 480V line-to-line and feeds a 100 meter section of the road. Although this document primarily uses the term roadway to refer to roads, it is intended to generally include surfaces that carry or support vehicles or similar mova...

Abstract

20 301198658_1.DOC:WEJ:wej Abstract A circuit for energising a magnetic flux coupling apparatus (109) has a pick-up coil (103) for receiving power inductively, a storage capacitor (124) for storing energy from the received power, and an inverter (125) 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.

Description

technical field [0001] The present invention relates to systems for inductive power transfer. The invention has particular application to powering an electric vehicle from the road on which said vehicle travels. It is also suitable for other wireless power applications. Background technique [0002] The problem of inductively providing electrical power to moving objects such as vehicles moving along roads has been discussed for many years in an attempt to overcome range concerns associated with pure electric vehicles (EVs), ie electric vehicles that rely solely on electrical energy. The ability to provide power continuously, or at least frequently enough, while the vehicle is in motion has many benefits. These benefits include: minimizing on-board energy storage and vehicle weight; and eliminating long charging times that are required when available power sources are dispersed and are only used when the EV's power supply is low. [0003] Inductively charging or powering e...
