Can you link something that explains this more?

Thanks! Seems like a lot of people (both here on lemmy and elsewhere) recommend synology

Knowing my track record for completing projects.. turnkey is probably best for me. Haha

Seeing a loooot of recommendations for Synology

I've had some heartache with Plex's categorization system too, on English language content nonetheless..

I cant imagine the pain of making it work for foreign content.

You tease

Good explanation.

As @directive0 said, the diodes (triangles in the above circuit) only conduct in one direction.

On the AC wave (top left) in the positive half, two diodes are conducting. In the negative half, the other two diodes are conducting.

The two sets of diodes are connected so that the positive half and the negative half of the sine wave come out on the same line. Since the waveform on the right of the image is all positive (ignore the bumps), it is considered DC.

You could get an output, but if you want to take 100Vdc and turn it into 10Vdc.. it will not do this... for this you will need a buck, sepic, buck-boost, cùk, resonant, or some other converter..

In the case of the rectifier:

if you look at a simple AC to DC converter (half-wave rectifier) either output = 0 volts or output = input - conduction losses, depending on how you polarized the DC source.

In another circuit (full wave rectifier), the diodes will be polarized such at two will allow current flow. output = input - conduction losses

If the rectifier is something more complex (12 pulse rectifier).. this circuit relies on transformers. If you put DC on the primary of the transformer then the output will be 0 volts and thus the rectifier output will also be 0 volts. In this example I've ignored the fact that the transformers have 3 terminals and the DC source would only have 2.

I'm less knowledgeable of more elegant rectification methods (such as active rectification)...

Interestingly.. the fundamental DC to AC converter (inverter) is the same circuit as the full wave rectifier, with the diodes replaced with controllable switches (SCRs, IGBTs, IGCTs, MOSFETs, ect.)

You can tell she had no idea what to expect. haha
