Abstract
Official abstract text for this publication.
An IPT pick-up circuit includes a resonant circuit including a pick-up inductor and a tuning capacitance in parallel with the pick-up inductor, a control system to control power transfer to the pick-up circuit and a power conditioning impedance provided in series between the resonant circuit and the control system, selected to provide a required power factor in the resonant circuit.
First claim
Opening claim text (preview).
I claim: 1. An IPT pick-up circuit comprising: a resonant circuit comprising a pick-up inductor and a tuning capacitance in parallel with the pick-up inductor; a control system to control power transfer to the pick-up circuit, the control system comprising a rectifier system; and a power conditioning impedance comprising an inductive element provided in series between the resonant circuit and the control system, the power conditioning impedance passing alternating current from…
