What Are False Zero-Crossings?
False zero-crossings are when the controller thinks it has detected a zero-cross event—but it’s actually responding to a transient or harmonic distortion, not a real zero-cross. When we keep in mind the differences between clamping vs. frequency attenuation surge suppression, false zero-crossings become a perfect example of where basic surge suppression fails spectacularly—and where high-performance […]
