There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total ...

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 ...

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 ...

The demands on power supplies have increased in recent years, which have resulted in the adoption of digital control as the latest trend in AC-to-DC and DC-to-DC power-conversion applications. Digital ...

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 ...
