[![enter image description here][1]][1] In the above image, I'm trying to understand the statement that says this is center tapped transformer is less efficient and the current is twice what it would be for a true full-wave circuit. I also have an LPSpice and inductor quesiton later? I did not print the full wave bridge circuit that was on the prior page. In that circuit, it looked like the transformer was 1 to 1 (not step up or down). In figure 1.75, the center tapped transformer looks like it steps the voltage up 2X, except that each half the voltage is 1/2. If this is so, the voltage would be the same as the non stepped up transformer in the full wave bridge circuit that the book might have refered to (and I tried to model below). I was trying to use ltspice to see current and voltage to get a sense of why it is less efficient, but didn't see that? [![enter image description here][2]][2] In this LTspice sim, i did not show the transformer that looks to be 1 - 1 . I spent time testing voltages. When I test the voltage on either side of V1, it does not ever go negative, is this because of the diodes? If so, what happens, when V1 tries to go negative and instead goes positive? [![enter image description here][3]][3] In this image, VI, tested between R2 and the + sign, oscillates between +160 and -160. When I test between R2 and L1, the negative drops out. I only get values between 0 and +160 through time. Where did the negative part of the wave go? I suspect that its because of the diodes on the right side of the circuit, but don't understand how this "decoupled " side affects the negative waveform on the left side of the image? The above is the center tapped transformer. If the negative part of the input drops off, then I can see how this transformer could be working harder. Any ideas on what happened to the negative partof the wave? [1]: https://i.sstatic.net/SkfZV.jpg [2]: https://i.sstatic.net/XJEeF.jpg [3]: https://i.sstatic.net/QlpHh.jpg
