Inductive power transfer pick-up with separate AC and DC outputs

摘要

589865 Disclosed is an inductive power transfer system (IPT) pick-up. The pick-up includes a pick-up coil (L2), a tuning capacitor (C2) associated with the pick-up coil (L2), a first output and a first control means (Buck Converter) associated with the first output (across DC Load). The pick-up coil (L2) is capable of generating a voltage by magnetic induction from a primary conductive pathway. The tuning capacitor (C2) in association with the pick-up coil (L2) provides a first pick-up resonant circuit. The first control means (Buck Converter) is associated with the first output (across DC Load) to substantially control the voltage or current provided by the first output (across DC Load). The pick-up also includes a further resonant circuit connected in series or parallel with the first pick-up resonant circuit and a second output (across AC load) associated with a second control means (Parallel Mode AC-AC Controller) to control the voltage or current provided by the second output (across DC Load).
