6.2.
Coupling decoupling network
The decoupling part of the coupling network has to:
- filter the interference pulses in the direction to the power supply;
- protect other systems that are connected to the same power supply and
- realize a high impedance of the power supply, e.g. battery supply.
6.2.1.
Coupling/decoupling network for ac/dc power lines
The coupling network has to couple the interference pulses to the lines of a power supply system (AC or DC). As
coupling devices capacitors of sufficient strength and bandwidth shall be used according to IEC 61000-4-18.
