What is the antiresonance effect in power supply capacitors?
The antiresonance effect can be a bug or a feature. In the case of DC link capacitors in high-frequency converters, it’s a bug that can decrease performance. But antiresonance in ultrasonic transducer power supplies is a feature used for efficient, stable power delivery under varying loads. Beyond the resonant frequency of a capacitor, parasitics in […]
