  • A Study of the Influence of ACMains Impedance and FrequencyDomain EMI Evaluation Methods on EMI Measurements

    One of the problems in EMI (electromagnetic interference) is poor reproducibility in measurements. This report is divided into three parts. In Part I, this paper shows that the real conducted noise can't be measured by a LISN (line-impedance-stabilization network) and a 50 ?>-input-impedance instrument, as specified by regulations such as those of CISPR (International Special Committee on Radio Interference). This is based on the generation mechanism for conducted noise on AC mains, generated from the AC-operated EUT (equipment under test). In Part II, it is pointed out that one of the causes of poor reproducibility in radiated-emission measurements is the difference among the line impedances of the AC mains. A VHF/UHF LISN (called Maeda's LISN) is introduced as a method to solve the poor reproducibility. In Part III, it is clarified that in evaluating the noise (including both conducted and radiated noise) represented in the frequency domain, the frequency spectra of noise, measured at different times for the same EUT, are different. This is shown by proposing a model to analyze the measured results obtained by the measurement method specified by the regulations.

  • Microshield Lines and Coupled Coplanar Waveguide

    This chapter is broadly divided into two types of transmission lines: microshield lines and coupled coplanar waveguides. Analytical equations to compute the characteristic impedance of microshield lines of various shapes are presented and discussed. Analytical equations to compute the even- and odd-mode characteristics of edge coupled coplanar waveguides without a lower ground plane are also presented. A discussion of conductor-backed edge coupled coplanar waveguides and broadside coupled coplanar waveguides concludes the chapter.

  • Z-Source/Quasi-Z-Source AC-DC Rectifiers

    Active rectifiers are attractive as an interface for ac-dc conversion for use in electric vehicle charging, because of their high efficiency and bidirectional operation. This chapter discusses the voltage-fed Z-source and quasi-Z-source rectifier, which improve the voltage boosting capability of the traditional voltage source rectifier, are immune to short-circuit of the phase legs, and are able to conduct both inverter and converter modes bilaterally. When analyzing the dc side, the rectifier bridge is equivalent to a current source. From simulation results of phase voltages and currents, it can be seen that unity power factor is obtained through the control method, in both inverter and rectifier modes. The quasi-Z-source rectifier was further taken as an example to illustrate their steady-state operating principles, dynamic modeling, control scheme, and simulation results, providing the fundamentals for the future development of such rectifiers.

  • Inductance Phenomena

    Inductance as a property of electrical systems, and specifically designed in a component such as an inductor, reactor, or transformer presents hazards to people who are working on the equipment or systems. The first hazard may be coming in contact with the energized conductors. Another important hazard is induced currents in conductive materials, which may cause electrical shocks, arcing, and heating. The inductance of an open-wire line increases as the conductors are separated. Infinite separation, as in a one-wire line, would mean infinite inductance. The skin effect is not strictly a form of inductance, but a frequency effect on resistance. The skin effect changes the internal inductance of a solid conductor, because the conduction occurs along the surface, making the inductance approach that of a tube rather than a cylinder. The surge impedance will determine the ratio of voltage and current for a transient wave traveling down the line.

  • The Smith Chart

    This chapter develops the Smith Chart by beginning with why the Smith chart works! This provides not only a theoretical derivation of the chart but physical insight into its basis and use. The fact that reflection coefficient magnitude changes in angle only (not magnitude) on a lossless transmission line is shown to be a way to determine the input impedance to a mismatched line, and that this underlies the use of the Smith chart. It is shown how contours of constant resistance and reactance in the rectangular impedance plane are mapped to the reflection coefficient plane by the bilinear transformation relating impedance to reflection coefficient, resulting in the Smith chart. Impedance and admittance Smith charts are presented, with load tuning examples. Slotted line measurements, which underlie standing wave theory, are demonstrated. Numerous practical techniques are presented, including: reading VSWR as r, negative resistance Smith charts, navigating the chart on constant radius (reflection coefficient) or constant resistance (reactance tuning) contours, using Smith chart software, estimating tuning bandwidth, use of approximate tuning for broader bandwidth, reading frequency contours on the chart, using the chart without transmission lines (arbitrary Z o), constant Q circle tuning, and graphical means for tuning and for finding lumped equivalent circuits (as for lengths of transmission lines).
