Psfb leading leg
WebThe leading leg is where the power device turns on after energy circulation, whereas the lagging leg increases after energy transfer. S1 and S2 power devices turn on after energy circulation- that’s why it is correct to name them Leading Leg. In contrast, S3 and S4 power devices turn on after the energy transfer forming the Lagging Leg. http://vmg-electronics.com/PSFB.pdf
