Real-Time Power Factor Correction (RTPFC)

Thyristor-Switched Dynamic Reactive Power Compensation

RTPFC systems use solid-state thyristor switches to connect and disconnect detuned capacitor steps at zero voltage crossing. This eliminates mechanical contactor wear, eliminates high inrush currents, and compensates rapid reactive load swings within 5-20 milliseconds.

Transient-Free Thyristor Switching

Ideal for Dynamic Industrial Loads

Standard electromechanical APFC contactors require 30 to 60 seconds discharge time between switching cycles, making them incapable of following rapid load variations such as welding machines, stamping presses, hoists, and cranes. RTPFC solves this with instant zero-crossing thyristor switching.

Zero voltage crossing switching with zero inrush transient current
Extends capacitor cell lifespan by avoiding switching surges
Equipped with 7% / 14% detuned harmonic suppression reactors
Maintains 0.99+ power factor even under rapid 1-second load cycles
