Power Supply 220v To 12v Dc Converter Circuit Diagram

Generating low voltage dc from the 220v or 110v ac mains is very useful and necessary in the field of electronics.

Power supply 220v to 12v dc converter circuit diagram.

220v to the 12v dc converter circuit diagram. Low voltage dc like 5v 6v 9v 12v is used in electronics circuits led bulbs toys and many household electronics items generally batteries are used to power them but they need to be replaced time to time which is not cost effective and also takes our time energy. 1n4007 has a peak repetitive reverse voltage of 1000v with an average rectified forward current of 1a. The output of any circuit fully depends on input voltage supply and it should be constant.

220v to 12v dc converter circuit diagram here four general purpose rectifier diode 1n4007 is used to rectify the ac input. The above ac dc converter circuit is simple and the transformer is used to step down the 230v ac to 13v ac. In many electronics projects we see that there is a requirement of fixed voltage power supply fixed means no fluctuation in voltage. Here four general purpose rectifier diode 1n4007 is used to rectify the ac input.

A classic 555 timer chip identified as ic1 is configured as an astable multivibrator at a frequency close to 100 hz which can be adjusted accurately by means of potentiometer p1.
