Linear Power Supply Power Factor and Passive PFC

Описание: In this video I discussed some of the misconceptions around the power factors of linear power supplies and demonstrated simple passive PFC technique with simple LC filters.

01:07 Linear power supply power factor
03:21 Power factor with no smoothing capacitor
05:23 Passive power factor correction with LC filtering
07:29 Why linear power supplies typically don’t use PFC
