TDK improves PFC efficiency

Power factor correction (PFC) can be more efficient at partial loads, according to UK power supply firm TDK-Lambda, which has patented its technique.

PFC is a technique employed in mains power supplies to prevent them injecting harmonic distortion into the mains (see box below).

However, “the switching loss in…
