Abstract
The invention relates to a circuit arrangement for providing a unit recognizing system combined with energy supply. The system includes a unit recognizer combined with energy supply (EE) and an energy source with variable frequency (FMG). The unit recognizing module combined with energy supply (EE) includes a supply block (3) and between this and the energy source with variable frequency (FMG) a further filter block (1) and a potential separating block (2).

Circuit arrangement for providing a unit recognizing system combined with energy conversion comprising a unit recognizing module combined with energy conversion (EE) having an input connected to the output of at least one remote frequency-modulated supply unit (FMT) through an energy supply line,
- the unit recognizing module combined with energy conversion (EE) is comprising a supply block (3), the supply block (3) including at least a circuit generating and/or controlling a supply voltage,
- characterized in that
- between the input (IN) of the unit recognizing module combined with energy conversion (EE) and the input (IN) of the supply block (3) there are a filter block (1) and a potential separating block (2) provided in commutative series electrical connection, where
- the filter block (1) comprising at least one filter stage including at least one element in each filter stage, the element being a band pass or a low-pass or a high-pass or a band rejection filter element, and
- the potential separating block (2) is including at least one transformer (TR) provided with at least one primary coil and at least one secondary coil.
A unit-recognizing and energy conversion unit comprising:
- a filter for selecting by passing or rejecting a signal from a supply line, whereby the unit is recognized, and a potential separator including at least one transformer in commutative series electrical connection with the filter, whereby one of the filter and potential separator is connected to the supply line and the other of the filter and potential separator is in series with the one thereof;
- and
- a power supply responsive to the other of the filter and potential separator, whereby to provide power from the recognized unit.
In a system having devices connected to a supply line, the improvement for selecting and powering one of the devices wherein the one of the devices includes a unit-recognizing and energy conversion unit comprising:
- a filter for selecting by passing or rejecting a signal from the supply line, whereby the unit is recognized, and a potential separator including at least one transformer in commutative series electrical connection with the filter, whereby one of the filter and potential separator is connected to the supply line and the other of the filter and potential separator is in series with the one thereof;
- and
- a power supply responsive to the other of the filter and potential separator, whereby to provide power to the one device from the recognized unit.
