Power supply device for e.g. proximity sensor in manufacturing robot, has monitoring device bypassed and/or loaded depending on resonance coils during considered time period of voltages produced by coils or criteria of resonance coils

摘要

The device has a monitoring device (13) bypassed and/or loaded in dependence of resonance coils (1, 2, 3) during a considered time period of voltages produced by the resonance coils or a criteria of the resonance coils, such that no contribution is provided for the power supply. The monitoring device includes a control electronics that receives the produced voltages and a reference voltage on an input-side and controls switches for bypassing the resonance coils on an output side.
