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 ...
The document describes an isolated high power factor (PF) TRIAC dimmable LED driver designed to drive a nominal LED string voltage of 41 V at 350 mA from an input voltage range of 90 VAC to 132 VAC.
Power factor correction (PFC) converters play a pivotal role in modern power electronics by ensuring an optimised alignment between the input current and the supply voltage. This alignment enhances ...
