Power Factor Correction (PFC), Texas Instruments


Texas Instruments integrated controllers for Power Factor Correction (PFC) in pre-regulators and PFC converters can achieve near unity power factor and give stable, low distortion sinusoidal line currents. They utilise Advanced features and innovative processes such as quantized voltage feed-forward, current synthesis, frequency dithering and slew rate enhancement to provide significant performance enhancements.

Power Factor Correction (PFC), Texas Instruments


Texas Instruments Power Factor Correction (PFC) controllers meet IEC61000-3-2 harmonic current limit standards. PFC controllers are designed for AC-DC applications and provide high Power Factor (PF), low current distortion (iTHD), high efficiency and high power density.
