AC Power-in

For powering the PLC and kinds of motor drives or operation machines,  the implemented ACDC power converter has to be scalable up to several KWs,  thus PFC (Power Factor Correction) and LLC converters (or equivalent isolated soft-switching topologies) are normally populated for achieving high PF (Power Factor) and low harmonics (THD – Total Harmonic Distortion or THD+N) as well as higher power effi-ciency, to be compliant with specific EMC regulations and power qualities.
