Power Supply

DC power is the basic need for any electronics project to start. Though batteries are good for small projects and also recommended due to the stable supply of current. But with increased power demand for more sophisticated projects batteries don’t seem a very good option to work with. A good bench supply or power adapter is handy and can be easily procured, but there is no match for custom-tailored design, specifically suited for the need. This is the story of a DIY two-channel 120W twelve volts fixed DC power supply.
