1. An inductive power transfer system (IPT) pick-up comprising:
- a pick-up coil capable of generating a voltage by magnetic induction from a primary conductive pathway, and a tuning capacitor associated with the pick-up coil to provide a first pick-up resonant circuit;
a first output associated with a first control to substantially control a voltage or current provided by the first output;
a further resonant circuit connected in series or parallel with the first pick-up resonant circuit; and
a second output associated with a second control to control a voltage or current provided by the second output.

Abstract
An inductive power transfer system (IPT) pick-up comprises:
- a pick-up coil capable of generating a voltage by magnetic induction from a primary conductive pathway, and a tuning capacitor associated with the pick-up coil to provide a first pick-up resonant circuit;
- a first output associated with a first control means to substantially control the voltage or current provided by the first output;
- a further resonant circuit connected in series or parallel with the first pick-up resonant circuit; and
- a second output associated with a second control means to control the voltage or current provided by the second output.
A method of providing an additional independently controllable output from an IPT pick-up having a resonant pick-up circuit is also disclosed.
