General Technical Information

2.2

Interference sources and disturbed equipment

Interference source

An interference source is an electrical device or electrical equipment which emits electromagnetic

interference. We can differentiate between two main groups of interference sources corresponding

to the type of frequency spectrum emitted (fig. 5).

Interference source (emission)

Discrete frequency spectrum

(Sine-wave, low energy)

Continuous frequency spectrum

(Impulses, high energy)

µP systems

RF generators

Medical equipment

Switchgear (contactors, relays)

Household appliances

Gas discharge lamps

Power supplies and battery chargers

Ignition systems

Welding apparatus

Motors with brushes

Oscillating drives

Atmospheric discharges

Data processing systems

Microwave equipment

Ultrasonic equipment

RF welding apparatus

Radio and TV receivers

Switch-mode power supplies

Frequency converters

UPS systems

Electronic ballast circuits

Sources of interference

Interference sources with discrete frequency spectra (e.g. high frequency generators and micro-

processor systems) emit interference energy which is concentrated on narrow frequency bands.

Switchgear and electric motors in household appliances, however, distribute their interference en-

ergy over broad frequency bands and are considered to belong to the group of interference sources

having a continuous frequency spectrum.
