In the previous articles, we assumed that the descriptions of DC/DC converters were ideal, neglecting the effect of parasitic elements. Thus, it is important to note that inductors have capacitive and ...

Last month's column covered the behavior of electrical components connected in series and demonstrated that when a voltage is applied across a series circuit, the current through each component is the ...

What is an LLC resonant power converter? Different approaches to LLC converter architecture. The half-bridge version of an LLC resonant converter. Modern-day power-management designs demand ever ...

This Power Tip shows you how to do a quick conversion of parallel-to-series complex impedances (and vice versa). It also shows that a graphical representation of this transformation as a function of ...

Many power supplies spend much of the time at loads far below their maximum and/or where they have the greatest efficiency, so improved efficiency is frequently required in normal and lower-power ...

A well-known solution for electrical noise in industrial plants is the constant-voltage transformer, or CVT. These devices can filter distortion and notches from input voltages (see Fig. 1). CVTs have ...
