INDUCTIVE POWER TRANSMISSION DEVICE
First Claim
1. A power transmission device (200) for inductive energy transfer, wherein the power transmission device (200) comprises:
- a first stage (210) adapted to be connected to a supply input voltage and adapted to convert the supply input voltage to an operating voltage;
a second stage (220) including a resonant circuit (221) connected to the first stage and adapted to generate an oscillating voltage from the operating voltage so as to generate a magnetic field for inductive transfer of energy from the power transmission device (200) to a target device (240);
a control circuit (230) connected to the second stage (220), the control circuit being adapted to detect a parameter value of the second stage (220) and adapted to start or stop amplification of the resonant circuit (221) based on the detected parameter value.

Abstract
A power transmission device for inductive energy transfer. The power transmission device comprises a first stage adapted to be connected to a supply input voltage and adapted to convert the supply input voltage to an operating voltage. The power transmission device further includes a second stage comprising a resonant circuit connected to the first stage and adapted to generate an oscillating voltage from the operating voltage so as to generate a magnetic field for inductive transfer of energy from the power transmission device to a target device. A control circuit is connected to the second stage. The control circuit is adapted to detect a parameter value of the second stage and is adapted to start or stop amplification of the resonant circuit based on the detected parameter value.
