Friwo Geratebau Gmbh

Tobias Pomp-Melchers

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.
