Parallel-tuned pick-up system with multiple voltage outputs
Abstract:
A pick-up is provided for an Inductively Coupled Power Transfer (ICPT) system having a parallel tuned resonant pick-up circuit. The pick-up has a plurality of independently controllable power supply outputs. This allows a first output to supply a high voltage load (e.g. 300V-550V) and one or more additional outputs for supplying other loads such as control circuitry which may only require 24V. The one or more additional outputs may be supplied via a current transformer connected in series with the resonant pick-up circuit. Control for each output may be achieved by partially or completely decoupling the pick-up from a primary conductive path of the ICPT system.
