Power Factor Correction is a technique of shaping input current to be as sinusoidal as possible to reduce harmonic distortion and associated losses and in-phase with input voltage in an AC circuit to have a power factor close to one. Placed as a front end in relatively high-power switch mode power supplies (SMPS), a three-phase power factor corrector is designed with a number of different topologies to meet specific requirements.

Our products and solutions

ST's extended offer of advanced PFC digital controllers and high-performance STM32 microcontrollers support interleaved and bridgeless topologies.  To help design robust and high-efficient PFC stages, these devices embed all the required protection features including output overvoltage, brown-out, feedback disconnection and boost inductor saturation. 

Developers will also appreciate our power MOSFETs and rectifiers including silicon-carbide (SiC) galvanically isolated gate drivers and a range of hardware and software evaluation and development tools.
