1.	The output dc voltage of an LC filter is_______(a) VDC=2Vm/π + IDCR(b) VDC=Vm/π – IDCR(c) VDC=2Vm/π – 2IDCR(d) VDC=2Vm/π – IDCRThis question was posed to me in an international level competition.I'm obligated to ask this question of L-Section Filter in section Application of Diodes of Electronic Devices & Circuits
Answer» Right option is (d) VDC=2Vm/π – IDCR Best explanation: The VALUE for VDC is same as that of inductor filter. If inductor has no dc resistance, then VDC=2Vm/π. If R is the SERIES resistance of TRANSFORMER, then VDC=2Vm/π – IDCR.
