Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

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 ...

Excessive use of electricity and poor efficiencies are no longer acceptable. Eliminating poor power factor will result in increasing electrical efficiencies and will reduce the overall use of ...

The power supply voltage requirements in smartphones and tablets are growing due to a constant increase in functionality. And that is leading to a rise in the number of inductors in power supply ...

Inductors are often overlooked, but they help manage energy and smooth out current in electronic circuits. This video explains what they do and why they’re essential in power supplies, audio equipment ...

Ask any electronics hobbyist or professional what the simplest building blocks of electronic circuits are, and they’ll undoubtedly say resistors, capacitors, and inductors. Ask a mechanically-inclined ...
