This paper proposes how to analyze and design the line impedance stabilization network (LISN). The details are described component characteristics and how to design air coil inductors in single and multi layers based on a high self resonant frequency response concept. According to the CISPR 16-1 standard, the stabilized impedance 50 Omega of LISN at(More)
The analysis and design of line impedance stabilization network (LISN) is presented. The details will be described how to design and stabilize the impedance of LISN at frequency range 150 kHz to 30 MHz following CISPR 16-1 standard. The impedance response of passive components: resistor, inductor and capacitor will be measured to identify the component(More)
Design and implementation of a low cost comb generator based on a BJT switching circuit are proposed in this work. The proposed comb generator can produce multiple harmonics with excellent amplitude flatness up to 2 GHz. The output power of each harmonic is −35 dBm at the low frequency end and −41 dBm at the high frequency end. The input of(More)
This paper presents the trade-off between EMI separator and the RF current probe for conducted EMI measurement. EMI toolkit is used as a noise source for investigating effects from differential-mode (DM) and commonmode (CM). Paul-Hardin noise separation network or EMI separator is used as a benchmark to compare with the RF current probe. The conducted(More)
This paper presents a new device for testing and investigating conducted disturbances with simultaneous key parameter measurements. The common and differential modes form line and neutral are simultaneously measured to provide the proper common and differential modes levels. Design techniques for a line impedance stabilization network are focused on the(More)
