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 ...

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 ...

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 ...

Wireless power transfer (WPT) enables device charging without direct physical or wired connections. Resonant circuits are key components of WPT systems that optimize energy transfer from the ...
