What is the formula for Vdc of a Center tapped full wave rectifier?
0.636*Vac - Vk (where Vk is the potential drop across a single diode. Assume both diodes have the same cutoff voltage)
or is it
0.636*Vac - 2Vk
It's not given anywhere in my textbook and I couldn't find it on the internet either. Logically the first one makes more sense to me because for every half-cycle, input voltage is across just one diode unlike in a full wave bridge rectifier where the input voltage is across two diodes.
