These specifications define not only the type of test, but also the technical requirements for the test instrumentation.In particular, in the field of low-frequency conducted phenomena, an AC/DC-voltage source is required for almost all types of test. In order to comply with these requirements a 4-quadrant amplifier has been developed which is based upon a linear push-pull design. Some of the remar-kable features of this amplifier design include it’s ironless output stage, extensive use of negative feedback over all amplifier stages, an extended frequency range and a very low internal resistance. FIELD OF APPLICATION Extremely low harmonic distortion EUT with switched-mode po-wer supply and non-linear current consumption (Fig. 1) need a very stable voltage source. The non-linear cur-rent characteristic of EUT with peak current flow in comparison to the harmonic limits according to the stan-dard IEC/EN 61000-3-2 are shown in Fig. 2. The voltage source meets the extremely rigorous require-ments of the international standard IEC/EN 61000-3-2, even under very non-linear load conditions. The waveshape of the output voltage is stable at any time (Fig. 3). The analysis of the harmonic content of the vol-tage source output signal when connected to a non linear load shows Fig. 4.

The PAS series of voltage sources are prepared to meet the requirements of additional standards such as: IEC/EN 60146-1-1 IEC/EN 61000-2-2 IEC/EN 61000-4-4 IEC/EN 61000-4-5 IEC/EN 61000-4-8 IEC/EN 61000-4-11 IEC/EN 61000-4-13 IEC/EN 61000-4-14 IEC/EN 61000-4-17 IEC/EN 61000-4-27 IEC/EN 61000-4-28 IEC/EN 61000-4-29 IEC/EN 61000-4-34 IEC/EN 61131-2 IEC/EN 61496-1 IEC/EN 61800-3 IEC/EN 62040-2 SEMI F47-0706 Long life expectancy and high reliability The PAS – series is the perfect programmable voltage source for all your test equipment and production line requirements. Fig. 11: 3-phase Grid Simulator DM 30000 Control To control the amplifier a range of different oscillators, including IEEE 488 control (e.g. SyCore, DDS units), are available. www.spitzenberger.de/weblink/1002
