if you are referring to a split-phase transformer, the answer is a Westinghouse engineer, C. F. Scott, in the late 1890's to bypass Edison's more expensive rotary-converter and thereby permit two-phase generator plants to drive Tesla's three-phase motors.

What is the difference between an ordinary transformer and a center-tapped transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
Why cant you implement centre tapped full wave rectifier without centre tapped transformer?
The center tapped full wave rectifier depends on two similar windings, each 180 degrees out of phase with respect to each other. You are only going to get that with a center tapped winding. Without the center tap, you need four diodes.
What replaces a EM48-23B-N transformer?
I suppose it depends on what you are repairing, I just replaced this exact transformer in a vintage Mr. Christmas Carousel Calliope. It is a 6v center tap transformer, I replaced mine with the one below which can be found on Amazon and is a 1amp. My carousel works good as new. I hope this helps someone.

What are the disadvantages of a bridge rectifier?
One segment goes out, you replace the whole thing. They tend to build up a little extra heat since they're all crammed into a single package. To avoid problems, use a bridge that will only run at half capacity. Meaning, if your device is pulling 1 amp, use a 2 amp bridge. And USE A HEAT SINK!!! and don't forget the heat sink grease.
Why am you losing half the voltage when rectifying secondary side of center-tapped transformer to DC via two 1n4007 diodes?
I think the answer is: if you input voltage to a grounded center-tapped secondary transformer winding, only 1/2 the voltage is applied to each rectifier at a time (sine wave), therefore the rectified voltage measured would be 1/2 that of the total voltage. The peak voltage would be 1.4 x RMS. Hope this helps.
Where are center tapped transformers used?
The transformer that feeds your house is a center tapped transformer. Primary 7200, Secondary 240. The 240 volt secondary is center tapped to give you 120 volts on either side of the tap. Hence house voltage is 120 / 240 volts.
What is the difference between the center tapped transformer and ordinary transformer?
An ordinary transformer has two input/output terminals but a center tapped transformer has 2 input and 3 output terminals. One is taken from the center for a ground connection. This causes it to get 50% of the actual value. And ordinary transformer contains 2 windings. An autotransformer has one.
If the loads were only 240v on a single phase 240v system with a center tapped transformer the neutral conductor would carry?
If a load were only 240 volt on a single phase 240v system with a center tapped transformer the neutral conductor would carry no current.

Who is better among centre tapped rectifier and bridge rectifier?
It depends on what you're doing and what you have available. If you can find a good center tapped transformer with the target voltage, that will save you 2 diodes. If you're going for the "quick and dirty" solution and you don't have a center tapped transformer, a bridge rectifier is an excellent way to get dirty DC. ANSWER: The center tap will offer a .7 v advantage over the bridge. Be aware that power output does not change just the voltage increases
Why can't we implement the center tapped full wave rectifier without center tapped transformer?
A center-tapped transformer and two diodes can form a full-wave rectifier that allows both half-cycles of the AC waveform to contribute to the direct current, making it smoother than a half-wave rectifier. This form of circuit saves on rectifier diodes compared to a diode bridge, but has poorer utilization of the transformer windings. Hence we do not use centre tapping for full wave rectification.Ashish sharmaAstt. ProfessorHIET, Shahpur, kangra(H.P.)
Why diodes are used after center tapped transformer in dc to ac inverter?
Diodes are used after a center-tapped transformer in a DC to AC inverter to rectify the alternating current (AC) output of the transformer into pulsating direct current (DC). This rectified voltage is then smoothed using filters to produce a more stable DC waveform. The diodes act as one-way valves, allowing current to flow in only one direction, thus converting the AC voltage into a pulsating DC voltage.
Why to use four diodes when two diodes also can serve the purpose in bridge rectifier?
Four diode rectifier not require a center tapped transformer.
Why are center tapped transformers used in North America?
Center tapped transformers are used in North America to be able to use two voltages from the transformers secondary. It is known as a three wire system. Appliances circuits that utilize 240 volts and appliances that use 120 volts can be supplied from one transformer. The transformers secondary is center tapped and grounded. This allows the 240 volt winding L1 - L2 to produce 120 volts from one leg of the winding to ground L1 - N and the second half of the winding 120 volts from N - L2. <<>> Center tapped transformers are used anywhere world wide where ever they were designed to be used. There is nothing particular to a center tapped transformer that makes it more or less suitable for use in North America.
Can you put transformers in series to double your voltage?
You can if done carefully. The neutral of one transformer must be set up to be at the positive voltage of the other transformer. This might require an intermediate step transformer that is center tapped (so three instead of 2 transformers).
Is there any application where center tap rectifier is preferred over bridge rectifier?
For a center tapped full wave rectifier transformer secondary gives a voltage that is 2Vm. For a bridge rectifier it is Vm.
