3 emc compliance is now a fundamental element of the electrical/electronics equipment design process, with legislation in europe to make compliance obligatory. this section provides an introduction to interference and noise limits - using the influential european standards as an example - with an introduction to the three main forms of choke components and their application. permissible noise limits the various standards set down limits for conducted emi emissions. these limits are measured in voltage and given in db? where 0db is 1?. 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 impedance stabilization network (lisn) - which gives a defined impedance to the noise and also helps filter any noise on the mains which may affect the measurements. 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 limits for en 50081-2, which is the european generic standard for the industrial environment. above 30mhz, radiated noise interference is measured as radiated noise instead of conducted noise. this takes place on an open field test site using defined antennas. figure 1. permissible interference limits for en 50081-1 interference sources and spectrums 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 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 semiconductor devices. interference spectrums generated can be either continuous, as in the case of phase angle controllers (see figure 3), or discrete (see figure 4), which is typical of an smps. figure 4. discrete spectrum 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 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. 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. 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. interference types to understand the problems associated with conducted emi it is first necessary to understand the two modes of conducted propagation: differential mode (symmetrical mode) and common mode (asymmetrical mode). differential mode interference appears as a voltage between the phases of the system and is independent of earth; the differential mode currents flow along one phase and return along another phase (see figure 5). common mode noise appears as a voltage between each phase and earth. the common mode currents flow from the noise source to earth (usually via a general information on emc and filter design using discrete chokes 0.15 frequency (mhz) 0.5 5 30 level (db v) 66 79 73 60 quasi-peak average industrial level (db v) 66 quasi-peak average light industrial & domestic 46 56 0.15 frequency (mhz) 0.5 5 30 60 50 56 46 frequency hz level db frequenz hz pegel db level db frequency hz figure 2. permissible interference limits for en 50081-2 figure 3. continuous spectrum
