Optimize AC circuit efficiency with our comprehensive range of Power Factor Correction (PFC) controllers. These advanced integrated circuits align voltage and current phases using average current mode, boundary conduction mode, and adjustable 6kHz–1.7MHz switching frequencies for industrial and energy systems.
Our PFC controller ICs deliver superior power quality and energy efficiency across a wide range of AC-DC power conversion applications. By minimizing reactive power and improving power factor to near-unity levels, these controllers reduce energy waste, lower utility costs, and ensure compliance with international power quality standards including IEC 61000-3-2 and Energy Star requirements.
Key Features:
- Wide switching frequency range (6kHz to 1.7MHz) for design flexibility
- Multiple control modes: average current mode, critical conduction mode (CrM), and boundary conduction mode (BCM)
- High power factor achievement (typically >0.99) with low total harmonic distortion (THD)
- Comprehensive protection features: overvoltage, overcurrent, overtemperature, and brown-out protection
- Wide input voltage range supporting universal AC input (85-265VAC)
- High efficiency operation reducing heat generation and improving system reliability
- Integrated gate drivers and control logic for simplified design
Applications:
- Switch-mode power supplies (SMPS) for industrial equipment
- Server and telecom power systems
- LED lighting drivers and ballasts
- Battery chargers and UPS systems
- Motor drives and variable frequency drives (VFD)
- Renewable energy inverters and converters
- Consumer electronics and home appliances
- Medical and laboratory power equipment
Technical Advantages:
Our PFC controllers enable designers to meet stringent harmonic regulations while maximizing power conversion efficiency. The adjustable switching frequency allows optimization for specific applications—lower frequencies for high-power industrial systems minimize switching losses, while higher frequencies enable compact designs with smaller passive components for space-constrained applications.
Each PFC controller IC undergoes rigorous qualification testing to ensure reliable performance in demanding environments including aerospace, automotive, telecommunications, and industrial automation systems.
