Fig 1. shows the conducted emissions of a switched pape mode power supply which has no suppression - components. The conducted emissions exceed the standards from 35 KHz to over 10 MHz. The effect of inserting an RS choke of the line can be seen in Fig. 2. Fig. 1 Emissions level of aS.M.P S_ without Below 100 kHz the narrowband differential mode suppression device peaks have been significantly reduced. Differential mode suppression is the strong point from choke series RS 500. A significant reduction in emissions is also noted above 3 MHz. At the choke self resonance frequency of 1.5 MHz an CLASS A increase in emissions Is noted To reduce this effect other suppression components would be used. | class 8 By using this choke with other components a complete suppression of this power supply can be achieved as shown in Fig 4. Fig. 2 Suppression effect of a RS 522-05 Multilevel attenuation Process in a S.M.P.S. Usage of dedicated discrete suppression devices, rT like symmetrical mode attenuation chokes (RS 500, Suppressor network RS 600 series) and/or asymmetrical mode with IEC connector (SN _) attenuation chokes, (RN 100, RN 200 series) and/ or capacitor suppression network (SN 9223, SN 223) allow the designer to build multistage filtering. Each stage works in a specific frequency area, or noise mode, see fig. 3. This added flexibility has been made feasible with the proper design of the 3 above mentioned Schaffner product families. Build to work together and optimized for perfect interaction, this combined with the freedom to select capacitance and inductance values they ; : a allow fast and efficient design for high volume Fig. 3 A typical discrete filtering assembly production equipment In our example the result is shown on fig. 4.

The low dc resistance and use of low loss cores makes these chokes ideal for low current power supplies operating at high switching frequencies. The recommended connection for the chokes in storage mode is a series connection as shown. - oL e oL iii _ a - since they are on the same core, this is equivalent to . 4x o_o Care must of course be taken to ensure that the dot convention is observed. Example of the selection of storage chokes: Consider a simple Buck converter with the shown values: Viy OF Assume Vin = 3O0V L= 2.5 Vin Vo Vour = 1 2Vv EN | = 1 A fewn (Vot Vin) ly for f switch = 25 kHz, required choke L = 857 wH RS 522-1-02 (900 WH) for f switch = 48 kHz, required choke L = 446 uH RS 514-1-02 (460 LH) for f switch = 100 kHz, required choke L=214uH RS 512-1-02 (230 wH) At higher switching frequencies the required choke becomes smaller, however there Is an increased likelihood of higher interference levels By using 48 kHz frequency a medium sized choke canbe used and the 3rd harmonicis at 144 KHz which is just below the critical EMC frequency of 150 kHz lf the 3rd harmonic is over 150 kHz. There may be a need for large suppression elements. The advantage of small storage elements can be lost due to an increase in filtering requirements.

The IEC (International Electrotechnical Commission) is a non governmental organisation responsible for preparing standards and recommendations for the Electrotechnical industry, like !SO (International Standards Organisation) is for most other area of activities. IEC standards and recommendations are adopted as regulations by national and international bodies such as: UL, VDE, BSI for their respective countries and by CENELEC (Comit Europen de Normalisation Electrotechnique) to cover member states of the EC (European Community). IEC 950 is a safety recommendation covering "Informa- tlon Technologie" and "Electrical Business" machines Therefore IEC 950 covers: small and large computers, faxes, copiers, typewriters and the many other types of equipment available in a business environment IEC 950 does not specifically mention power line filters but as filters are components in most of the above mentioned equipment, several aspects of IEC 950 have a direct effect on power line filters design, test, measurement and specifications. IEC 950 Specifications - what are they? Schaffner IEC 950 compatible filters fulfill IEC 950 requirements in the following way: IEC 950 BASIC and SUPPLEMENTARY INSULATION for TN and TT power distribution systems. High potential tests rated at 2,125 VDC (1500 VAC test 1s not recommended for capacitor reliability reasons) this phase to neutral, phase to housing, or, neutral to housing. Test duration ts 60 secs at the system qualification level, as well as at the component qualification level. For production of equipment or of filter this test is only carried out for 1 sec or more at 80 % of the rated value. IEC 950 leakage current The Schaffner filters have been designed to produce less leakage current than the maximum permitted In most cases, allowance for additional leakage from the equipment is included. This to meet all the mobility equipment type of the IEC 950 class 1. IEC 950 discharge time All filters have a phase to neutral discharge of less than 1 second. This meets the requirements for all classes of equipment, pluggable as well as permanently installed. IEC 950 - How to get your system tested and approved? Approving equipment to IEC 950 with power line filters implies a system test at 2125 VDC (or 1500 VAC) test for 60 secs. During these tests the discharge resistors, when they exist, are many times overloaded !EC 950 allows this test to be carried out without these resistors. For such tests, filter without the discharge resistor can be supplied. They are the FN xxxxT types. RS 500 and RS 600 do not require special "T" units for system tests Filters for other IEC 950 requirements For other IEC 950 requirements such as 3 kV test for reinforced insulation or the 4 kV test to earth for "IT" earthing applications, please contact your nearest Schaff- ner sales office to obtain a specially designed or specified filter based on the original standard type. Please note that changes in dimension may result due to the increased insulation requirements.
