How to Make a Stabilized Power Supply
Having discussed using transformers for stepping down the voltage up to the desired limits, you should know that the operation does not merely end there. The lowered voltage is still AC and entirely undesirable for using with an electronic circuit. The delivered power needs to be made into a DC and filtered thoroughly to make it ideally compatible with electronic circuits.
The process of making AC into DC is called rectification. The main components engaged with rectification of the applied AC from a transformer are fundamentally the diodes: the rectifier diode and the zener diode. An LED is also a diode, however the part is better known for its light emitting abilities and therefore used as voltage indicators for indicating the presence of a DC voltage and other similar visual indications.
Modern power supplies heavily involve voltage regulator ICs which help to enhance the voltage quality dramatically. Interestingly, all these parts are also active electronic components serving for the other connected electronic circuits.
