Will the voltage change after the rectifier transformer is rectified?

In the use of DC power supply, people will still choose the input and output of the loop transformer to be used for alternating current. The main reason is that the loop transformer has the advantages of high efficiency and low temperature rise, and can't help asking whether the voltage will change after the transformer is rectified.
In general, the voltage will change after the rectifier, the voltage will rise 1.1-1.414 times after the rectifier filter, for example, the voltage after the rectifier is 24V, the voltage before the rectification filter should be 20V more appropriate.
But the size of the voltage after the transformer rectifying filter is related to the size of the filter capacitance and the size of the actual load. When the capacity of the filter capacitor is large enough, the maximum voltage of the transformer after rectification can reach 1.414 times that of the original rectifier.

If the transformer is only rectified without filtering, the DC voltage after rectification will be smaller than that before the original rectifier, which is equal to the voltage drop of the AC voltage minus the rectifier diode. The calculation methods of different rectifier bridges are different, and several kinds of DC voltage algorithms are simply listed below.
1, bridge rectifier: reduce the voltage drop of 2 diodes, 2*0.7V=1.4V (single winding output is usually used in this way).
Such as: AC220V to AC24.5V AC ring transformer only rectifier does not filter, DC voltage =AC24.5V-1.4V=23.1V.
2, full wave rectifier: reduce the voltage drop of 1 diodes, 1*0.7V=0.7V (full wave rectifier general input of three lines, such as the common double 12V is full wave rectifier).
3, half wave rectification: reduce the voltage drop of 1 diodes, 1*0.7V=0.7V (half wave rectification because efficiency is too low, circuit design is not commonly used).
To sum up, the voltage of the loop transformer will change after rectification, and the voltage after rectification and filtering will be greater than that before the original rectifier. The voltage of the rectifier without filtering will be smaller than that before the original rectifier, and the voltage changes in different rectifying modes are different.
