An unregulated full wave DC supply circuit is a full wave rectifier followed by a capacitor or capacitor/inductor filter, but there is no regulator following it.
The full wave rectifier is either two diodes running from a center tapped transformer winding (or some kind of split phase power such as 120/240), or it is four diodes in bridge configuration running from a normal (non-tapped) transformer winding (or some kind of single phase power).
The no-load output voltage will be the peak rectification voltage. The loaded output voltage will have ripple, extending from the peak rectification voltage down to the level provided by the filter just prior to the rectifiers turning back on in the next AC cycle. The ripple frequency will be twice the supply frequency, i.e. 120 hz for a 60 hz supply.

simplified circuit for three phase cycloconveretr?
They both have the same current.
to get maximum dc output
Right: Example out of a transformer AC to DCAnother Answer:Anywhere there is AC and DC is required. A full wave rectifier is a circuit that produces a DC pulse using both halves of an AC sine wave - full wave rectifier.
A full wave rectifier is a component or set of components that change AC waveforms into DC. It is frequently used as part of a power supply circuit and therefore it is often directly adjacent to a transformer. However, a transformer is used to provide a suitable AC voltage and is not part of the rectifier.
Output voltage is higher!!!
A full-wave rectifier circuit converts both halves of an AC waveform into a pulsating DC output, which can lead to a more efficient use of the power supply. The operation of the full-wave rectifier affects the power factor by allowing the load to draw current during both halves of the AC cycle, resulting in reduced harmonic distortion and smoother current flow. This improves the power factor compared to half-wave rectification, where current is only drawn during one half of the cycle, leading to increased reactive power and lower efficiency. Consequently, full-wave rectifiers can enhance overall system performance in applications like power supplies and motor drives.
A full-wave rectifier will provide an output through both the positive and negative halves of the AC sine wave. The half-wave rectifier will only provide an output for half the cycle. The filtered outputs of both rectifiers can be "smoothed" well, but the higher the load on the half-wave rectifier, the more the output voltage will vary across a cycle of input power. This results in higher ripple and makes regulation a bit more difficult. The full-wave rectifier will provide an output through both the positive and negative halves of the sine wave. It effectively "inverts" the negative half of the cycle and provides two "pulses" of power per cycle as opposed to one pulse per cycle for the half-wave rectifier. The full-wave rectifier might use a pair of diodes and a center tapped transformer, or might use four diodes in a full wave bridge configuration and a transformer with no center tap.
There is an article in Wikipedia which gives full details on how rectifiers work - including circuit diagrams. See related link.
