emc concepts explained

This is the second in a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

This is the first of a series of articles devoted to the design, test, and EMC emissions evaluation of 1- and 2-layer PCBs that contain AC/DC and/or DC/DC converters and employ different ground techniques.

This article presents a concept of a wave together with the wave equations and their solutions.

This article discusses the reflections on a transmission line terminated with either an RL or an RC load.

This article discusses the current distribution for the stripline configurations.

This article discusses the distribution of a PCB return current underneath top trace for the microstrip configuration. Next month’s article will discuss the distribution for the stripline configurations.

This article discusses the common-mode and differential-mode radiation from cables and presents the measurement results from the SMPS connecting wires.

This article discusses the basics of a step-down (buck) DC Switched-Mode Power Supply (SMPS). It should serve at an entry-level tutorial and a building step towards the more advanced designs.

Part II of this two-article series focuses on log-periodic and biconical antenna impedance, VSWR, and radiated emissions measurements.

This two-article series is devoted to a dipole family of antennas used in EMC testing: half-wave dipole, quarter-wave monopole, log-periodic, and biconical antenna.
