Simplified power factor correction: Sensorless control could enable smaller, more reliable electronic adapters
Single-phase power factor correction (PFC) circuits—a kind of front-end AC/DC converters—are ubiquitous in a variety of consumer electronic devices, including laptop adapters, LED driver power ...
Power Factor Correction (PFC) is becoming an integral piece of a power conversion system, particularly for high power systems. This webinar will explain reasons for poor power factor and look at ...
This paper presents a novel approach to control a boost PFC AC/DC converter without using any current sensors. Due to the particular structure of the boost PFC AC/DC converter, sensorless control of ...
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 ...
