JEOLLANAM-DO PROVINCE, South Korea, Dec. 18, 2025 /PRNewswire/ -- Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer ...

Understanding power factor (PF) is important because it gives us a clear understanding of the efficiency of an electrical system. Put simply, it’s the ratio of true power and apparent power, which ...

Researchers develop a sensorless boost PFC method delivering near 0.9998 power factor and low distortion, enabling smaller and more reliable power supplies for consumer electronics. Single-phase power ...

A new reference design developed by ROHM Semiconductor uses a single microcontroller (MCU) to control both sides of the AC-DC power supply — the power-factor-correction (PFC) AC-DC converter stage and ...

Active current shaping using flyback ac-to-dc converter provides power factor control and dc voltage regulation. Distributed power supplies will be the new architecture for next generation PCs and ...

Ideally, the power factor should be 1; then the load appears as a resistor to the AC source. However, in the real world, electrical loads not only cause distortions in AC current waveforms, but also ...
