Center-tapped rectifier without diodes?

In summary: Vcc, then -...-....-....-....-....-....-....-....-....-....Vdd and so on.In your second diagram you have labelled the coil voltages vi wrongly.

Yes sir, I have taken that comment on board. I understand that if we can make any other non-linear component work as a switch, it should work as a rectifier. However, my main concern was, with the original circuit diagram still in mind, why couldn't we use ANY component for the purpose?

Thankfully, my question has been answered for equal resistors. All the posts have been very informative, and I've been religiously following this thread for any new comments. :D

1.) these components have to be non-linear. If you use R' L' and C's, you will get nothing (if the bridge is balanced) or you will get AC (in some phase and amplitude or another) if it's not.

2.) you presumably want the rectification to be reasonably efficient, so just any old non-linear component wouldn't be a lot of use for the purpose. You need something that, ideally, has zero resistance for one half of the cycle and infinite resistance for the other half. A good diode does the job best.

^ I understand these. My point was still related to the current path. I didn't understand why alternately working switches are necessary for producing a unidirectional current through the load, since my mistakes were leading me to believe that any component should be able to do the job based on the configuration and assembly of the circuit alone (which, I admit, is stupid). It was the third terminal, a.k.a the center-tap that caused all my confusion. It's the first time I've encountered a circuit involving three terminals.

1. What is a center-tapped rectifier without diodes?

A center-tapped rectifier without diodes is a circuit that converts alternating current (AC) into direct current (DC) without the use of diodes. It uses a transformer with a center-tapped secondary winding to split the AC input into two equal halves, which are then combined to produce a DC output.

2. How does a center-tapped rectifier without diodes work?

The center-tapped rectifier without diodes works by using the center-tapped transformer to create two half-wave rectified outputs. The two outputs are then combined through a filter circuit to produce a smoother DC output. This process is known as full-wave rectification.

3. What are the advantages of using a center-tapped rectifier without diodes?

One advantage of using a center-tapped rectifier without diodes is that it is a simpler and cheaper circuit compared to a full-wave rectifier with diodes. It also has a higher efficiency and produces less ripple in the output voltage.

4. What are the limitations of a center-tapped rectifier without diodes?

A center-tapped rectifier without diodes has a lower output voltage compared to a full-wave rectifier with diodes. It also has a lower output current capability and is not suitable for high power applications.

5. How is a center-tapped rectifier without diodes different from a full-wave rectifier with diodes?

A center-tapped rectifier without diodes uses a transformer to split the AC input into two halves, while a full-wave rectifier with diodes uses four diodes to convert the entire AC input. Additionally, a center-tapped rectifier without diodes has a lower output voltage and current capability compared to a full-wave rectifier with diodes.
