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 […]
How do ML and AI work in power conversion: part 2
This article digs into how machine learning (ML) and artificial intelligence (AI) contribute to the optimization of green energy systems and electric vehicles (EVs). It looks at a few of the ways ML/AI enable designers to deploy dynamic models that learn from experience, and handle non-linearities and changing, complex conditions better than fixed algorithms. Part […]
