Harmonic Mitigation Solutions
Reduce Harmonic Distortion. Improve Power Quality.
Harmonics are unwanted electrical distortions generated by modern nonlinear loads like VFDs, UPS systems, rectifiers, and automation electronics. ActiveSine's Active Harmonic Filter (AHF) continuously detects and cancels harmonic currents in real-time, delivering clean sine-wave power and IEEE 519 compliance.
3-Level Topology Active Harmonic Filter
Why Harmonic Mitigation Matters
Nonlinear loads draw current in non-sinusoidal pulses, injecting harmonic frequencies (3rd, 5th, 7th, 11th, etc.) back into your distribution system. Without mitigation, these currents distort the supply voltage.
Overheating & Thermal Stress
Harmonic currents cause severe eddy current and hysteresis losses in transformers, motors, and neutral conductors, leading to premature insulation breakdown.
Nuisance Tripping & Malfunctions
Voltage distortions result in spurious tripping of protective circuit breakers, false sensor triggers, and erratic PLC/automation behavior.
Capacitor Bank Failure & Resonance
Harmonic amplification can trigger parallel and series resonance, catastrophically overloading standard capacitor banks.
Utility Penalty & Non-Compliance
Failure to comply with grid utility harmonic limits (IEEE 519 / CEA standards) leads to heavy penalties and disconnection risks.
Active Harmonic Filter (AHF) Closed-Loop Cancellation
ActiveSine AHF acts like noise-canceling headphones for your electrical network. Highly accurate current transformers (CTs) measure harmonic distortion in real-time. The digital signal processor (DSP) analyzes the waveform and commands the 3-level IGBT inverter to inject an equal and opposite anti-harmonic current, restoring the grid current to a pure sine wave.
