This section provides an introduction to interference and noise limits - using the influential 30 0.15 0.5 5 Frequency (MHz) European standards as an example - with an introduction to the three Figure 2. Permissible interference limits main forms of choke components for EN 50081-2 and their application. Permissible noise limits Interference sources and spectrums The various standards set down limits for The most common sources of conducted conducted EMI emissions. These limits are EMI are power electronic products such as measured in voltage and given in dBµV switched mode power supplies (SMPS), where 0dB is 1µV. The interference is pulse width modulated (PWM) frequency measured using a measurement receiver inverter motor drives and phase angle which has defined bandwidths and controllers. Interference propagation EMI can propagate by two means: • by radiation - where the energy can be coupled either through magnetic or electric fields, or as an electro-magnetic wave between the source and victim. • by conduction - where the EMI energy will propagate along power supply and data cables. Radiated and conducted EMI cannot be thought of as totally separate problems because noise conducted along a cable 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 impedance stabilization network (LISN) which gives a defined impedance to the 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 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 interference. Below about 100-200MHz, the most efficient radiators in a system are usually the power supply and data cables. Proper filtering of these cables will reduce radiation due to the cables as well as conducted interference. semiconductor devices. Above about 100-200MHz, PCB tracks and noise and also helps filter any noise on the Interference spectrums generated can be short internal cables will start to become mains which may affect the measurements. either continuous, as in the case of phase efficient radiators. To reduce this radiation angle controllers (see Figure 3), or discrete PCBs should be laid out to reduce track (see Figure 4), which is typical of an SMPS. length and loop areas; ground planes Figure 1 shows the limits for EN 50081-1, which is the European generic standard for residential, commercial and light industrial environments, and Figure 2 shows the should be used if possible.

The impedance of the choke at powerline frequencies is therefore negligible, resulting in practically zero Figure 7. Saturating choke in series with a thyristor Rod-cored chokes (RF Series) In contrast to saturating types, rod-cored chokes present a constant inductance. They are also suitable for attenuating differential-mode or symmetrical (P➔N) interference, particularly lower frequency interference up to around 500kHz. Single and dual rod-cored chokes are ideal for the construction of RFI suppression filters for the 150kHz frequency region of Figure 6. Common mode interference (VCM) voltage drop.

For optimum attenuation, ambient temperature and permissible chokes must be connected as close as current loading: • saturating chokes - which are ideal for reducing fast current changes • rod-cored chokes - which present a possible to the semiconductor switching constant inductance even at high device.
