Automatic Power Factor Correction (APFC) with Thyristor-Switched Capacitors
Industrial power factor controller calculating phase angle between voltage and current zero-crossings to switch optimal capacitor steps.
Project Overview
Eliminates electricity board utility penalties for inductive factory loads. Dual zero-crossing detection circuits feed microcontrollers that calculate displacement power factor (cos phi) and dynamically trigger solid-state thyristor switches to keep the power factor above 0.98.
