INDUCTIVE POWER SUPPLY, REMOTE DEVICE POWERED BY INDUCTIVE POWER SUPPLY AND METHOD FOR OPERATING SAME

摘要

An inductive power supply (9) includes a transceiver (28) for sending information between the remote device (11) and the inductive power supply. The remote device determines the actual voltage and then sends a command to the inductive power supply to change the operating frequency if the actual voltage is different from the desired voltage. In order to determine the actual voltage, the remote device determines a peak voltage (34) and then applies a correction factor.
