Radiated and conducted EMI cannot be

thought of as totally separate problems

because noise conducted along a cable

will, to some extent, be radiated because

the cable will act as an antenna. The

radiation will increase as the cable length

becomes comparable to the wavelength of

the noise. Also, the cable will act as a

receiving antenna and pick up radiated

interference.

The most common sources of conducted

EMI are power electronic products such as

switched mode power supplies (SMPS),

pulse width modulated (PWM) frequency

inverter motor drives and phase angle

controllers.

The various standards set down limits for

conducted EMI emissions. These limits are

measured in voltage and given in dBµV

where 0dB is 1µV. The interference is

measured using a measurement receiver

which has defined bandwidths and

receivers. The two receivers used are a

quasi-peak detector, and an average

detector. To ensure repeatability of the

measurements, the impedance of the

mains supply must be constant. The

standards calls for a defined artificial mains

network - sometimes called a line

The emissions spectrum typically starts off

very large at low frequency and rolls off as

frequency increases. The point at which

the noise falls below the permitted limits

depends on several factors, the most

important being the frequency of operation

and the switching time of the

which gives a defined impedance to the

noise and also helps filter any noise on the

semiconductor devices.

Above about 100-200MHz, PCB tracks and

short internal cables will start to become

efficient radiators. To reduce this radiation

PCBs should be laid out to reduce track

length and loop areas; ground planes

should be used if possible. Decoupling of

digital ICs is very important and shielding

may be necessary.

This type of component consists of a ring

Saturating-type chokes change

and can be used to attenuate differential-

devices such as thyristors and triacs.

Interference levels can be brought within

the limits of national and international

regulations by using these chokes in

conjunction with appropriate suppression

capacitors. For optimum attenuation,

chokes must be connected as close as

possible to the semiconductor switching

device. A simple single-stage suppression

circuit is shown in Figure 7; this can be

made into a dual-stage filter by the load

itself and one additional capacitor.

These chokes present a constant inductance, and are ideal for

attenuating differential-mode or symmetrical interference problems,

particularly at lower frequencies up to around 500kHz. They are

suitable for replacing saturating or current-compensated chokes in

higher power three-phase systems handling currents in 100A+ range.

The inductance of saturating-type chokes reduces as load current

increases, and is ideal for attenuating the differential-mode or

symmetrical interference generated by fast-switching thyristors, triacs,

transistors and phase angle control devices. Inductance values are

not shown because the leakage inductance is relatively high.
