Abstract
The DC regulated power supply is controlled by the power converter 、 Bridge rectifier filter circuit and voltage stabilizing circuit . The transformer will operate at power frequency 50Hz 220V The AC household power supply is changed into low-voltage AC power supply , Then the rectifier circuit is used to change the AC voltage into unidirectional pulsating DC voltage , Filter the AC component in the pulsating DC through the filter circuit . The voltage stabilizing circuit keeps the output stable DC voltage . This design mainly adopts DC voltage stabilizing circuit to form an integrated voltage stabilizing circuit , Through voltage transformation , rectification , wave filtering , The voltage stabilization process will 220V Alternating current (ac) , Change to a stable DC voltage , And realize that the voltage can be in 1.25V-37V Adjustable , The whole design consists of proteus Simulation Implementation .
