Electromagnetic (EM) radiation from inductors in DC/DC converters is no triviality — especially when considering the type and proximity of surrounding components and their susceptibility to magnetic coupling. In this post, we will discuss EM radiation as it pertains to unshielded, semi-shielded, and shielded inductors. We will also cover how EM radiation changes according to different influences.

Many engineers believe that there is a single inductor value that should be used for a given design. They may have read an application note, or a textbook, that sets the value of the current ripple in a buck converter, for example. I would caution becoming complacent in this technique.

The automotive electronics industry has responded to automotive application challenges by defining a component stress-test standard for passive components known as AEC-Q200. It includes a set of tests, some drawn from other standards bodies, which a device must pass for it to be qualified to AEC-Q200. What is this about?

Depending on the intended application electrical components are exposed to either transitory or permanent dynamic mechanical stress which can impair the performance (e.g. mechanically induced crack in PCBs systems or fretting corrosion in connectors and others).

This is the first of the two articles devoted to the topic of an RC snubber design. In Part I, we discuss the fundamentals of inductive switching and the need for circuit protection. The impact of an RC snubber on the circuit performance is demonstrated through a series of simulations. Part II (to appear in the March 2019 issue of In Compliance) will address the systematic process of the snubber circuit design, together with the simulation and verification through the laboratory measurements.

Modern measuring equipment, such as the HP4195A impedance analyzer and similar instruments, allow computer-aided derivation of equivalent circuits and their optimization. Constant parameters for inductance L, capacitance C, and resistance R are required for the simulation of electronic circuits. An incorrect approach in defining an equivalent circuit leads to flawed or incorrect simulation results.

A potential is induced in a conductor loop if the magnetic field passing through the conductor loop changes with time. The surge in potential over the area of the loop is known as the magnetic induction B. Like the magnetic field strength, the magnetic induction B is a vector quantity.
